Description
The D4 control valve with easy-Drive electric actuator is a compact, rugged valve designed primarily for high‐pressure
throttling applications. This valve is ideal for use on pressure and flow control applications within the oil and gas
production industry. The D4 valve also makes an excellent dump valve for high‐pressure separators and scrubbers.
The D4 control valve meets the metallurgical requirements of NACE MR0175/ISO 15156 without environmental limits
for temperatures below 135_C (275_F). If the temperature is above 135_C (275_F), the N07718 Belleville washers will
impose some limits, as shown in table 3.
Specifications
Table 1 lists specifications for the D4 control valve with easy-Drive electric actuator. Some of the specifications for a
given control valve as it originally comes from the factory are stamped on a nameplate located on the lower actuator
enclosure.

Installation
WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.
To avoid personal injury or property damage caused by bursting of pressure‐retaining parts or by uncontrolled process
fluid, be certain the service conditions do not exceed the limits shown on the valve nameplate and in table 1. Use
pressure‐relieving devices required by government or accepted industry codes and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
WARNING
For explosionproof applications, ensure the actuator cover is properly bolted before applying power to the actuator.
Personal injury or property damage may result from fire or explosion if power is applied to the actuator with the cover
removed in a hazardous area.
For explosion‐proof applications, install rigid metal conduit and a conduit seal no more than 457 mm (18 inches) from the
actuator. Personal injury or property damage may result from explosion if the seal is not installed.
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection, and
temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
CAUTION
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve
materials with process media rests solely with the purchaser and end‐user. Since some body/trim material combinations
are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve without first
contacting your Emerson sales office
To avoid product damage, inspect the valve before installation for any damage or any foreign material that may have
collected in the valve body. Also remove any pipe scale, welding slag, or other foreign material from the pipeline.

WARNING
Avoid personal injury or property damage caused by possible actuator failure. The use of a rigidly‐mounted support on the
actuator casing may cause additional stress on the actuator leading to premature wear and/or failure of the actuator
components.
CAUTION
To avoid product damage, inspect the valve before installation for any damage or any foreign material that may have
collected in the valve body. Also remove any pipe scale, welding slag, or other foreign material from the pipeline.
1. Before installing the control valve assembly, inspect it for any damage and for any foreign material that may have
collected in the valve body.
2. Remove any pipe scale, welding slag, and other foreign material from the pipeline.
3. The control valve can be installed in any position, but normally the actuator is vertical above the valve. Install the
valve so the flow direction arrow on the side of the valve indicates the direction of the process flow.
4. Install the valve following local and national piping codes when they apply to the application. For screwed
connections, treat the external pipe threads with a good grade pipe compound. For flanged valves, use suitable
gaskets between valve and pipeline flanges.
5. If continuous operation is required during maintenance and inspection, install a conventional three‐valve bypass
around the valve.

If you are using the default inputs signals, and the valve has not been disassembled or adjusted in any way, there is no
need to recalibrate the assembly. You can proceed directly to Startup (page 18).
Changing the Inputs from Default Settings
All configuration within the valve is done by setting values in Modbus registers. This can be done using any Modbus
master (flow computer, PLC, PC). Configuration software, providing a visual interface to the registers, is available
through your Emerson sales office or the Fisher website, at www.fisher.com/easyDrive.
Modbus setup
Use of a serial or USB to RS-485 device is required to connect to the actuator. Refer to manufacturer's requirements for
installation. The D4 with easyDrive electric actuator Modbus factory defaults are Address 1, 9600 baud, even parity, 1
stop bit, MSB.
When a connection has been achieved, the actuator may be configured to accept the input signal over the Modbus
link (ignoring the physical inputs) and the Modbus settings may be changed to accommodate the network to which it
is attached. Other changes to functionality are possible, such as:
D Low level cutoff: 40054 (default is 5%)
D Position upon loss of signal: 40053 (default is 0%)
See Appendix A for a full map of Modbus registers and their functions.

Connecting using the Fisher easyDrive configuration software
The Fisher easyDrive configuration software allows configuration and diagnosing of the Fisher easyDrive electric
actuator with a graphical interface. Connect a PC to the actuator using a USB or serial device to Modbus RTU converter
using the wiring instructions above. The USB or serial device will be visible in the drop menu under Serial Port Settings.
Baud rate and parity should be set to the Modbus settings of the actuator. Default actuator settings are address 1,
9600 baud, even parity, 1 stop bit, MSB. Press the AUTO button in the upper left corner to connect to the valve.
Use the Fisher easyDrive configuration software (figure 10) to make the desired changes, or register values may be
changed to allow different functionality.
Note
If an actuator is on/off, a Modbus command of 0499 in register 40001 will cause the valve to close fully, while a value of 5001000
will cause the valve to open fully. The command register has one implied decimal point.
Initial Setup
The control method selection determines what control signal to which the valve will respond. Only the control signal
selected will result in movement of the valve; all others will be ignored. The control methods available are dependent
upon the licensing tier purchased with the valve. The functions for each tier are shown below.

D4 Valve with Gen 2 easy-Drive Actuator
April 2022
Instruction Manual
D104188X012
If an easy-Drive valve has been shipped from the Fisher factory, it is not necessary to perform a span calibration. If,
however, the valve has a new controller board or maintenance has been performed on the valve, such as trim
replacement, it will be necessary to perform a span calibration. A span calibration is accomplished by the following
method:
1. Ensure the process and valve are in a safe state – the valve may move during this operation
2. Press the CALIBRATE SPAN button to initiate the span calibration. The software will show a progress bar during the
calibration and display Valve Span Calibrated when complete.
Analog Input Calibration
For valves using 4-20 mA as a control source, several options are available to customize control of the actuator. Use a
4-20 mA signal generator to provide the desired signal. It is possible to calibrate the 4-20 mA signal in reverse acting or
split-ranging with the method below with at least 4 mA of signal difference between the close and open values. The
example shows a valve being changed from normal to reverse acting during the calibration process.
1. With the Control Method set to 4-20mA Positioning or 4-20mA Level, enter the Calibration screen and the
4-20mA Signal Calibration window will be visible.
2. Click the CALIBRATE CLOSE & OPEN VALUES button. A separate window will open to guide through the process.
3. Set the 4-20 mA signal to the desired value for when the valve is to be closed.
4. Enter this value into the Calibrated mA Signal text box and press Next
Figure 12.
5. Set the 4-20 mA signal to the desired value for when the valve is to be open.
6. Enter this value into the Calibrated mA Signal text box and press Next.
14
Instruction Manual
D104188X012
Figure 13.
D4 Valve with Gen 2 easy-Drive Actuator
April 2022
7. If the Close and Open values are as expected, press Confirm to accept these values. If not, press Cancel to restart
the process.
Note
The value of the 4-20 mA signal must have at least 4 mA difference between the close and open signals. A differential less than
that amount will cause the actuator to reject the calibration and use the previous values.
Should the entered values vary more than 10% from the expected 4-20 mA values; the actuator will accept the calibration and a
Notification displaying “Questionable Analog Calibration” will result.
Figure 14.
Calibration with the use of Modbus
1. After the unit has been properly wired and fused per instructions in the Wiring section of this instruction manual,
turn power to the unit on.
2. Calibrate using Modbus:
a. Send position command of 0% to actuator to prevent unexpected motion. Valve will move to commanded
position following the calibration procedure.
15
D4 Valve with Gen 2 easy-Drive Actuator
April 2022
b. Send a value of 1 to register 40043. Valve plug will move to fully open position and then to fully closed. The valve
plug will then return to the commanded position.
If a Modbus connection is not available, and recalibration is desired, use the appropriate calibration method as
determined by the control method of your valve.
Instruction Manual
D104188X012
Calibration without the use of Modbus
1. Turn power to the actuator off.
2. Wait for 10 seconds to ensure all circuits have discharged.
3. Return power to the actuator and use the appropriate calibration method for your control signal. Calibration
sequence must be done within 15 seconds of power being switched on.
4. For positioning operation using 4-20 mA:
c. Apply a 4 mA signal between pins 4-20 mA - and 4-20 mA +. If Span is currently uncalibrated, valve plug will not
move at this time.
d. Apply a 20 mA signal between pins 4-20 mA - and 4-20 mA +. If Span is currently uncalibrated, valve plug will not
move at this time.
e. Apply a 4 mA signal between pins 4-20 mA - and 4-20 mA +; valve plug will move to the upper stop, immediately
followed by moving to the lower, closed position.
f. If calibration of the analog input is desired to improve positional accuracy, an optional operation is listed on
page 14 titled Analog Input Calibration.
5. For On/Off operation using dual-input dry contact:
a. Close the contact to create a short between pins COMMON and CLOSE. If Span is currently uncalibrated, valve
plug will not move at this time.
b. Close the contact to create a short between pins COMMON and OPEN. If Span is currently uncalibrated, valve
plug will not move at this time.
c. Close the contact to create a short between pins COMMON and CLOSE; valve plug will move to the upper, open
position and then to the lower, closed position.
6. For On/Off operation using single dry contact:
a. Open the contact to create an open circuit between pins COMMON and OPEN. If Span is currently uncalibrated,
valve plug will not move at this time.
b. Close the contact to create a short between pins COMMON and OPEN. If Span is currently uncalibrated, valve
plug will not move at this time.
c. Open the contact to create an open circuit between pins COMMON and OPEN; valve plug will move to the upper,
open position and then to the lower, closed position.
7. The unit is now calibrated.
Licensing
The Gen 2 easy-Drive actuator has two differing modes of operation: On/Off and Positioning. The On/Off mode is
intended for snap-acting applications where the valve is either fully open or fully closed. In this mode, the valve plug
cannot remain at any intermediate position; it will move to a fully closed or fully open position only. For applications
that require the actuator to control over the full range of motion, it is necessary to have a Positioning license installed.
A positioning license will allow access to 4-20mA positioning, 4-20mA level control and Modbus positioning.
16
Instruction Manual

Start Up
WARNING
To avoid personal injury or property damage, be aware that the valve will move and respond to an input signal during start
up.
1. Before turning on power to the unit, be sure that a closed signal is being commanded to the unit.
D DryContact: contact is open.
D L2e (Dual Dry Contact): Contact closed across pins COMMON and CLOSE.
D Analog Input: signal = 4 mA.
D Modbus: position demand = 0.
2. Turn on power to the unit.
3. Apply a change in position demand to ensure unit responds properly.
D DryContact:
D Closed contact between pins COMMON and OPEN will open the valve.
D Dual contact / L2e only: Closed contact between pins COMMON and OPEN will open the valve. Closed contact
between pins COMMON and CLOSE will close the valve.
D Analog Input: valve will respond to proportional demand.
18
Instruction Manual
D104188X012
D Modbus: valve will respond to positional demand in register 40001. 0 = fully closed and 1000 = fully open.
4. If the valve does not respond as expected, proceed to Troubleshooting guide on page 19.
5. Check conduit ports.
D Conduit seal must be in place within 450mm (18 inches) of the enclosure.
D Unused conduit ports must be sealed with an explosionproof port plug.
6. Replace the cover and tighten all 8 bolts to 20 Nm (15 ftlbs).
D4 Valve with Gen 2 easy-Drive Actuator
Troubleshooting
1. Unit does not move.
a. Verify that 12VDC to 24VDC is present on the power terminals as shown on the cover. Green heartbeat LED will
pulse near Modbus terminals when power is present.
b. Verify that all wires are firmly attached on both ends.
April 2022
c. Verify that wires are connected to the correct terminals - see Wiring in the manual.
d. Verify mode of operation (on/off or positioning) matches control signal.
e. Verify mode of control (local or Modbus) matches control signal.
2. Unit does not respond to 420 mA signal
a. Verify that 12VDC to 24VDC is present on the power terminals as shown on the cover.
b. Verify that the 420 mA signal is wired correctly and that the terminals are firmly on the wires.
c. Verify mode of operation matches control signal (local control: 40067=0, positioning: 40065=1).
d. Check the value of the analog input in register 40026 to determine if it is 0 or greater.
i. If register 40026 shows 0, the 4-20 mA may be wired backwards. Swap wire and attempt again.
3. Diagnostics show a Motor Stall - Travel Deviation Fault.
a. The easyDrive electric actuator is designed to operate in a manner consistent with a pneumatic actuator. This
means that if the valve plug can not move to its commanded position, the actuator will stop, without damage,
and issue a Motor Stall - Travel Deviation Fault warning. When the command signal changes outside of the
deadband (Modbus register 40036), it will attempt to move again. Recalibrate the actuator span per instructions
in the Startup section of this manual.

Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection
and maintenance depends on the severity of the service conditions.
WARNING
Avoid personal injury from sudden release of process pressure or bursting of parts. Before performing any maintenance
operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the
actuator cannot suddenly open or close the valve.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure
on both sides of the valve. Drain the process media from both sides of the valve.
D Vent the power actuator loading pressure and relieve any actuator spring precompression.
D Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the
pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
WARNING
For explosionproof applications, ensure the actuator cover is properly bolted before applying power to the actuator.
Personal injury or property damage may result from fire or explosion if power is applied to the actuator with the cover
removed in a hazardous area.
Do not remove the actuator cover for 10 minutes after power is disconnected if the UPS option is installed.
For explosion‐proof applications, install rigid metal conduit and a conduit seal no more than 457 mm (18 inches) from the
actuator. Personal injury or property damage may result from explosion if the seal is not installed.
Select wiring and/or cable glands that are rated for the environment of use (such as hazardous area, ingress protection, and
temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage
from fire or explosion.
Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
Failure to follow the local, regional, and national codes could result in personal injury or property damage from fire or
explosion.
Valve Plug and Seat Ring
Disassembly
Key Numbers are referenced in figures 21 and 22.
1. Isolate the control valve from the line pressure, release pressure from both sides of the valve body (key 1), and drain
the process media from both sides of the valve.

D4 Valve with Gen 2 easy-Drive Actuator
April 2022
CAUTION
The following steps are intended to prevent damage to the valve plug (key 3) and seat ring (key 2) during the removal of the
bonnet and actuator.
2. For Positioning Actuators
•Command the valve to anywhere between 10% and 20% travel.
•Isolate power and signal.
•Proceed to step 3.
For ON/OFF Actuators
•Command the valve to open or close, and cut the power when the valve is at midstroke.
•Isolate power and signal.
•Proceed to step 3.
3. Break the hammer nut (key 6) loose with a hammer. Continue turning the hammer nut by using a hammer or a
large adjustable wrench, tightened around one ear of the hammer nut. If the bonnet is stuck on the valve, continue
to unscrew the hammer nut. The hammer nut will contact the spring pins (key 7) and will force the bonnet out of
the valve. Carefully lift the actuator, bonnet, and valve plug assembly from the valve body.
WARNING
The spring pins must always be in place during valve operation. They provide a safeguard against injury when the unit is
being disassembled.
4. Use a socket wrench to loosen the seat ring (key 3).
5. Remove the seat ring (key 3) and seat ring gasket (key 9) from the valve body.
6. To replace the plug, the stem nut (key 42) must be removed to expose the groove pin (key 4). Open the
explosionproof enclosure (key 60), using a 13 mm wrench.
7. Remove the stem nut (key 42) using a 11/16 inch wrench; insert a punch in the hole in the stem to restrict rotation
of the stem while removing the stem nut. The travel indicator (key 32) may need to be moved to expose the hole.
8. Push the stem downward just far enough to expose the groove pin (key 4) on the plug.
9. Remove the plug by driving out the groove pin and unscrewing the valve plug from the stem.
WARNING
Be careful to avoid damaging the seating surface on the valve plug or seat ring as damage in these areas will allow
excessive leakage at shutoff. Avoid damaging the highly polished valve stem surface. A damaged valve stem could cut the
packing and allow process fluid to leak to the atmosphere.

1. Make sure the bonnet O‐ring (key 8) is on the bonnet and lubricated with lithium grease (key 49).
2. Install the plug (key 2) on the stem (key 47) and insert a new groove pin (key 4).
3. Push the plug and stem upward to ensure the threads on the top of the stem are exposed. Thread the stem nut (key
42) onto the top of the stem and tighten the stem nut (key 42) to 39 N•m (29lbf•ft). Insert a punch in the hole in
the stem to restrict rotation while tightening the stem nut.
4. Replace the top of the explosion proof enclosure (key 60) and tighten cap screws (key 64) to 20 N•m (15 lbf•ft).
5. Thoroughly clean the seat ring and bonnet threads in the valve body (key 1). Also clean the valve body seat ring
gasket surfaces.
6. Apply anti-seize lubricant (key 54) to the threads of the seat ring (key 3), and its mating threads in the valve body.
7. Apply anti-seize lubricant (key 54) to the seat ring gasket (key 9) and install into the valve body.
8. Screw the seat ring into the valve body. Use a socket wrench to tighten the seat ring to the torque valves shown in
table 7. Remove all excess lubricant after tightening.
9. Lubricate (key 54) the threads on the valve body and hammer nut and the contact surfaces of the bonnet and
hammer nut flange. Install the bonnet and actuator assembly with pinned valve plug onto the valve body. Tighten
the hammer nut using an adjustable wrench until the nut stops turning. A few hammer blows will be required to
ensure the assembly is tight.
Valve Packing
WARNING
Observe the warning at the start of the Maintenance section.
The valve stem packing can only be accessed from within the valve body. If packing maintenance is required, first
disassemble per steps 1, 2, and 6 or 7 in the Valve Plug and Seat Ring Disassembly section of this document.
Note
Packing installation and adjustment is critical to the long-term packing performance. Absolutely no deviations from this procedure
are allowed.
To minimize friction and maximize sealing performance, a small amount of fluorinated grease (key 56) is placed
between the packing rings.
Single Packing Arrangement
The packing components are to be installed as shown in the assembly drawing per the following procedure:
1. Install packing spacer (key 48) in the packing box.

A memory fault has occurred and the actuator
has been restored to factory defaults. Contact
your Emerson sales office.
The actuator is unable to move to the
commanded position and has stopped. Follow
troubleshooting guide in Help section to remedy.
The digital input has detected a closed contact
and the actuator has moved to its safe position.
Check switch input device status.
The actuator has experienced a fatal error and
shut down. Contact your Emerson sales office.
The analog values entered do not match the
analog signal level. Check analog signal value and
value entered.
The valve travel distance is outside the
acceptable range. Confirm valve type and that no
obstructions are present.
The analog values for open and close are less
than 4 mA and previous values have been
maintained. Calibrate analog input with
differential >4 mA.
Actuator was powered down during a move and
actual position may vary from commanded.
Recalibrate the valve span.
Control signal not present. Signal is <3 mA,
timeout period exceeded (40051 or 40052).
