Failure to follow these instructions or to properly install and maintain this equipment could result in an explosion and/or re causing property damage and personal injury or death.

Fisher® regulators must be installed, operated and maintained in accordance with federal, state and local codes, rules and regulations and Emerson Process Management Regulator Technologies, Inc. (Regulator Technologies) instructions.

If the regulator vents gas or a leak develops in the system, service to the unit may be required. Failure to correct trouble could result in a hazardous condition.

Call a gas service person to service the unit. Only a qualied person must install or service the regulator.

Introduction

Scope of the Manual

This Instruction Manual provides installation, adjustment and maintenance instructions and parts ordering information for the 299H Series regulators. Complete

instructions and parts list for the 67C Series ltered pilot

supply regulator and other Fisher equipment are found in separate instruction manuals.

Description

The 299H Series pressure reducing regulators provide a broad capacity of controlled pressure ranges and capacities in a wide variety of distribution, industrial and commercial applications. A 299H Series regulator has a pilot integrally mounted to the actuator casing. The 299H Series regulators can handle inlet pressures

up to 175 psi / 12.1 bar depending on orice size.

Figure 1. 299H Series Pressure Reducing Regulator

The integral token relief on the Types 299HR and 299HSR regulators is located in the pilot and opens to relieve minor overpressure.

The Type 299HS provides overpressure or overpressure and underpressure protection by completely shutting off

the ow of gas to the downstream system. It comes with a Type VSX-2 slam-shut device which can be congured

for Ovepressure Shutoff (OPSO) or Overpressure and Underpressure Shutoff (OPSO/UPSO). The slam-shut device’s actions are independent of the main valve and of variations to the inlet pressure. The Type VSX-2 slam-shut device has internal or external registration. External registration requires a downstream sensing line.

Since a pilot-operated regulator is constructed of both a pilot and a main valve, do not exceed the maximum inlet pressure shown on the nameplate.

Letter keys in this section refer to Figure 2 unless otherwise noted. Fast response and accuracy are made possible by the amplifying effect of the pilot and by the two-path control system. The function of the pilot is to sense change in the controlled pressure and amplify it into a larger change in the loading

pilot diaphragm.

External registration—The throat (J) is blocked and a downstream control line is connected to the pilot upper diaphragm chamber or the actuator lower diaphragm chamber. A small port (G) connects the two chambers.

Dual registration—The lower main diaphragm chamber registers outlet pressure through the throat (J) and the upper pilot diaphragm chamber registers downstream pressure by using a downstream control line. The port (G) between the chambers is blocked.

pressure. Any changes in outlet pressure act quickly on both the actuator diaphragm and the loading pilot, thus providing the precise pressure control that is characteristic of a two-path control system.

Upstream or inlet pressure is utilized as the operating

medium, which is reduced through pilot operation to load the main diaphragm chamber. Tubing connects the inlet pressure to the pilot. Downstream or outlet pressure registers underneath the main diaphragm (E) and on top of pilot diaphragm (F). There are three different versions of pressure registration for the 299H Series.

Type 299H

In operation, assume the outlet pressure is less than the setting of the pilot control spring (A). The top side of pilot diaphragm assembly (F) will have a lower pressure than the setting of the control spring (A). The control spring (A) forces the diaphragm assembly

upward, opening the pilot orice (C). Additional loading pressure is supplied from the pilot orice to the top side

of the main diaphragm (E).

299H Series

This creates a higher pressure on the top side of the main diaphragm (E) than on the bottom side, forcing the diaphragm downward. This motion is transmitted through a lever, which pulls the valve disk (K) open,

allowing inlet pressure to ow through the valve.

When the demand in the downstream system has been

satised, the outlet pressure increases. The increased

pressure is transmitted through the downstream control line (for external or dual registration) or through the port (G) (for internal registration) and acts on top of the pilot diaphragm (F). This pressure exceeds the pilot spring setting and forces the diaphragm down, closing

the orice (C). The loading pressure acting on the

main diaphragm (E) bleeds to the downstream system through a bleed restriction (H).

With a decrease in loading pressure on top of the main diaphragm (E), the main closing spring (B) exerts an upward force on the diaphragm post which is connected to the main diaphragm (E), pulling it upward. This moves the main valve disk (K) toward its

seat, decreasing ow to the downstream system.

Type 299HR

During normal operation the Type 299HR performance is identical to the Type 299H. If an overpressure condition occurs, the pilot diaphragm head will separate from the pilot diaphragm post and travel until it contacts the pilot spring case. The movement of the diaphragm head creates a path and a token or small amount of gas will be released.

When the overpressure condition ceases, the pilot diaphragm head will return to the diaphragm post and the regulator will return to normal operation.

Type 299HS

The Type VSX-2 slam-shut device on the Type 299HS regulator is a fast acting slam-shut valve which provides overpressure or overpressure and underpressure

protection by completely shutting off the ow of gas to

the downstream system. The slam-shut module’s actions are independent of the Type 299HS main regulator and of the variations to the inlet pressure. The Type VSX-2 has internal or external registration. External registration requires a downstream sensing line.

The slam-shut disk is held in the open position (reset position) by a small ball holding the disk stem. If the pressure below the diaphragm increases (or decreases) reaching the Type VSX-2 setpoint, the diaphragm will travel upwards (or downwards) operating a lever which in turn releases the ball.

Once the ball is released, the spring force on the stem will push the stem and disk to the closed position

against the seat shutting off all gas ow. The pilot

supply pressure is also shut off when the Type VSX-2 is closed. The manual reset has an internal bypass to equalize the reset pressure on either side on the slam-shut disk.

In order for the Underpressure Shutoff (UPSO) of any slam shut to be triggered, the downstream pipe pressure must drop below the UPSO setpoint. In the case of a downstream line break, numerous factors can prevent the downstream pipe pressure from decreasing below the slam-shut UPSO setpoint. These factors include the distance of pipe to the break, the

diameter of the pipe, size of the break and the number

of restrictions, such as valves, elbows and bends, downstream of the regulator and/or slam-shut device. Due to these factors additional protections should be

installed to stop ow in the event of a line break.

Overpressure Protection

Like most regulators, the Type 299H has outlet pressure ratings lower than the inlet pressure ratings. Complete downstream overpressure protection is needed if the actual inlet pressure exceeds the outlet pressure rating.

Overpressure protection for internal parts is built into the main and pilot diaphragms by means of a small spring on each post. The springs will allow the diaphragm heads to move farther on the posts avoiding damage to or bending of the valve trim.

Overpressuring any portion of a regulator or associated equipment may cause leakage, parts damage or personal injury due to bursting of pressure-containing parts or explosion of accumulated gas. Regulator operation within ratings does not preclude the possibility of damage from external sources or from debris in the pipeline. A regulator should be inspected for damage periodically and after any overpressure condition.

The pilot vent is provided with a 1/4 NPT tapped connection in the spring case.

Installation

WARNING

Personal injury, equipment damage or leakage due to escaping gas or bursting of pressure-containing parts might result

299H Series

if this regulator is overpressured or is installed where service conditions could exceed the limits for which the regulator was designed or where conditions exceed any ratings of the adjacent piping or piping connections. To avoid such injury or damage, provide pressure-relieving or pressure-limiting devices (as required by the appropriate code, regulation or standard) to prevent service conditions from exceeding those limits.

A regulator may vent some gas to the atmosphere in hazardous or ammable gas service. Vented gas might accumulate and cause personal injury, death or property damage due to re or explosion. Vent a regulator in hazardous gas service to a remote, safe location away from air intakes or any hazardous location. Protect the vent line or stack opening against condensation or clogging.

If the regulator is exposed to an overpressure condition, it should be inspected for any damage that may have occurred. Operation below these limits does not preclude the possibility of damage from external sources or from debris in the pipeline.

If the Type VSX-2 is exposed to an overpressure condition, it should be inspected for any damage that may have occurred. Operation below these limits does not preclude the possibility of damage from external sources or from debris in the pipeline.

In the case of a downstream line break, numerous factors affect the capability to evacuate gas from the pipeline. These factors include the distance of pipe to the break, the diameter of the pipe, size of the break and the number of restrictions, such as valves, elbows and bends, downstream of the regulator and/or slam-shut device. Due to these factors additional protections should be installed to stop ow in the event of a line break.

Like most regulators, the 299H Series regulators have an outlet pressure rating lower than its inlet pressure rating. Complete downstream overpressure protection is needed if the actual inlet pressure can exceed the regulator outlet pressure rating or the pressure ratings of any downstream equipment. Regulator operation

within ratings does not preclude the possibility of damage from external sources or from debris in the lines. A regulator should be inspected for damage periodically and after any overpressure condition.

Clean out all pipelines before installation. Check for damage which might have occurred during shipment. Also, check for and remove any dirt or foreign material which may have accumulated in the regulator body.

Apply pipe compound to the external pipe threads of threaded bodies or use suitable line gaskets and good

bolting practices with a anged body. This regulator

may be installed in any position desired as long as the

ow through the body is in the direction indicated by the

arrow on the body. Install a three-valve bypass around the regulator if continuous operation is necessary during maintenance or inspection.

Although the standard orientation of the actuator and pilot to the main valve body is as shown in Figure 1, this orientation may be changed in 90° intervals by rotating the actuator lower casing (key 1, Figure 6) and

the elbow tting (key 19) by 90° and then reinstalling

the cap screws.

To keep the pilot spring case from being plugged or the spring case from collecting moisture, corrosive chemicals or other foreign material, the vent must be pointed down oriented to the lowest possible point on the spring case or otherwise protected. Vent orientation may be changed by rotating the pilot spring case with respect to the pilot body.

To remotely vent the pilot, remove the screwed-in vent assembly (key 27, Figure 5) from the pilot spring case and install obstruction-free tubing or piping into the 1/4 NPT vent tapping. Provide protection on a remote vent by installing a screened vent cap into the remote end of the vent pipe.

An upstream pilot supply line is not required because of the integral pilot supply tubing (key 21, Figure 6). However, as long as the 1/4 NPT tapping in the main valve body is plugged, this tubing may be disconnected from the main valve (key 17) in order to install a pilot supply line from a desired remote location into the pilot.

If using a control line, attach the control line from the pilot tap 2 to 3 feet / 0.61 to 0.91 meters downstream of the regulator in a straight run of pipe. If impossible to comply with this recommendation due to the pipe arrangement, it may be better to make the control line tap nearer the regulator outlet rather than downstream of a block valve. Do not make the tap near any elbow, swage or nipple which might cause turbulence. For optimal performance, use as large of a control line as practical.

299H Series

In many instances, it will be necessary to enlarge the

downstream piping to keep ow velocities within good

engineering practices. Expand the piping as close to the regulator outlet as possible.

WARNING

Adjustment of the pilot control spring to produce an outlet pressure higher than the upper limit of the outlet pressure range for that particular spring can cause personal injury or equipment damage due to bursting of pressure-containing parts or the dangerous accumulation of gases if the maximum actuator emergency casing pressure is exceeded. If the desired outlet pressure is not within the range of the pilot control spring, install a spring of the proper range according to the Maintenance section.

Each regulator is factory-set for the pressure setting

specied on the order. If no setting was specied,

the outlet pressure is set midrange of the pilot control spring. In all cases, check the control spring setting to make sure it is correct for the application.

Registration Conversion

To convert the 299H Series regulators from one type of registration to another, all that is required is adding or removing screws and O-rings.

To change an internal registration regulator to an external registration regulator with a downstream control line, block the two ports in the throat with screws and O-rings (J in Figure 2). Remove either the 3/4 NPT pipe plug in the pilot casing or the 3/4 NPT pipe plug in the lower casing and add a downstream control line.

To convert an external registration regulator to a dual registration regulator, remove the two screws and O-rings (J in Figure 2) from the throat and use a screw and an O-ring to block the port (G in Figure 2) between the lower diaphragm chamber and pilot diaphragm chamber. Remove the 3/4 NPT pipe plug in the pilot lower casing and add a downstream control line.

control line, block the body pitot tube with a screw and gasket (keys 10 and 11, Figure 7). Remove the pipe plug in the Type VSX-2 and add a downstream control line.

Type VSX-2 Installation

Note

The Type VSX-2 slam-shut module should be mounted so that the spring case vent points towards the ground.

Keys are referenced in Figure 7. Place new O-rings (keys 2 and 3) on the Type VSX-2 and slide the module into the Type 299HS body (key 17). Secure the Type VSX-2 to the Type 299HS body with the four set screws (key 4). The Type VSX-2 device may be oriented in any direction with respect to the sensor line connection.

Startup

With proper installation completed and downstream equipment properly adjusted, perform the following procedure while monitoring the pressure with gauges.

1. Very slowly open the upstream block valve.

2. On a Type 299HS, the Type VSX-2 is shipped in the tripped position and will need to be reset. If the Type VSX-2 is a high trip only, it can be reset before starting the regulator. If the Type VSX-2 is a high and low trip, the regulator will need to be started

and the downstream system pressurized before the

Type VSX-2 can be reset. See the section for Type VSX-2 reset.

3. Slowly open the hand valve (if used) in the control line. The regulator will control downstream pressure at the pilot control spring setting. See the Adjustment section following these numbered steps if changes in the setting are necessary during the start-up procedure.

4. Slowly open the downstream block valve.

5. Slowly close the bypass valve, if used.

6. Check all connections for leaks.

Type VSX-2 Slam-Shut Device

To convert the Type VSX-2 from one type of registration to another, all that is required is adding or removing a screw and gasket.

To change an internal registration Type VSX-2 to an external registration Type VSX-2 with downstream

Adjustment

Keys are referenced in Figure 4. The only adjustment on a 299H Series regulator is the reduced pressure setting of the pilot control spring (key 32). Remove the closing cap (key 29) and turn the adjusting screw

299H Series

(key 36). Turning the adjusting screw clockwise into the spring case increases the controlled or reduced pressure setting. Turning the screw counterclockwise decreases the reduced pressure setting. Always tighten the locknut (key 35) and replace the closing cap after making adjustments.

Type VSX-2 Reset

Note

The overpressure and underpressure trip points can only be reset if the Type 299HS outlet pressure is between the overpressure and underpressure trip points.

Use the following procedure to reset the Type VSX-2:

1. Unscrew the brass resetting knob to open the

equalizing bypass.

2. Pull out the knob until it stops. This resets the tripping mechanism.

3. Push in and tighten the knob.

Type VSX-2 Trip Adjustment

Note

An adjustment tool is included with the Type VSX-2 (see Figure 8). Use only this tool to make adjustments to the Type VSX-2. To make adjustments, the overpressure trip spring (key 7, Figure 7) is found under the outer adjusting screw and the underpressure trip spring (key 8) is found under the inner adjusting screw.

Use the following procedure to adjust the Underpressure Trip Spring:

1. Use the Type VSX adjusting tool to adjust the underpressure trip spring to its minimum compression.

2. Backpressure the unit with the desired underpressure trip pressure.

3. Increase the underpressure trip spring compression (using the Type VSX adjusting tool) until the Type VSX-2 trips.

Shutdown

Installation arrangements may vary, but in any installation it is important to open and close valves slowly and the outlet pressure be vented before venting inlet pressure to

prevent damage caused by reverse pressurization of the

regulator. Isolate the regulator from the system. Vent the downstream pressure; then vent inlet pressure to release any remaining pressure in the regulator.

Maintenance

Regulator parts are subject to normal wear and must be inspected periodically and replaced as necessary. The frequency of inspection and replacement depends upon the severity of service conditions and upon applicable codes and government regulations.

Due to the care Regulator Technologies takes in meeting all manufacturing requirements (heat treating, dimensional tolerances, etc.), use only replacement parts manufactured or furnished by Regulator Technologies.

WARNING

Use the following procedure to adjust the Overpressure Trip Spring:

1. Use the Type VSX adjusting tool to adjust the overpressure trip spring to its maximum compression (see Figure 8).

2. If present, adjust the underpressure spring (using the Type VSX adjusting tool) to its minimum compression.

3. Backpressure the unit with the desired overpressure trip pressure.

4. Reduce the overpressure trip spring compression until the Type VSX-2 trips.

Avoid personal injury or damage to property from sudden release of pressure or uncontrolled gas or other process uid. Before starting to disassemble, carefully release all pressures according to the Shutdown procedure. Use gauges to monitor inlet, loading and outlet pressures while releasing these pressures.

On reassembly of the regulator, it is recommended that a good quality pipe thread sealant be applied to

pressure connections and ttings and a good quality

lubricant be applied to all O-rings. Also apply an anti-

seize compound to the adjusting screw threads and

other areas as needed.

299H Series

Note

The regulator body may remain in the pipeline during maintenance procedures.

2. Carefully loosen and remove the double nuts (key 5) on the actuator diaphragm post (key 10). When removing the adjusting nuts, do not twist or unscrew the diaphragm post, as this action will loosen the joint between the diaphragm post and the pusher post (keys 10 and 11).

3. Remove the spring seat (key 4) and closing spring (key 6).

4. Remove the eight hex head cap screws (key 23) and lift off the upper casing (key 2).

5. Remove the diaphragm assembly (key 8) by tipping it so that the lever (key 26) slips out of the pusher post (key 11).

6. Separate the diaphragm assembly by unscrewing the diaphragm post (key 10) from the pusher post (key 11) and remove the diaphragm post,

pressure equalization spring (key 7), diaphragm

head (key 81), diaphragm (key 8), the second diaphragm head (key 81) and diaphragm pad (key 80). Inspect the diaphragm parts for damage and replace if necessary.

7. Inspect the lever (key 26) and replace if necessary. To replace the valve stem (key 16), also perform

Main Body Valve Disk and Orice maintenance

procedure steps 1, 2 and 3, remove disk (key 13) and pull the stem out of the lower casing assembly (key 1). Lightly lubricate the replacement stem O-ring (key 14) and install it on the valve stem. Reinstall the valve stem into the lower casing assembly. Reinstall the body (key 17) or continue with the reassembly of the diaphragm.

Note

8. Loosely reassemble the diaphragm and diaphragm post parts so that the bolt holes in the diaphragm align with the corresponding holes in the lower

casing (key 1) when the lever (key 26) is tted

properly into the pusher post. When this orientation is made, tighten the diaphragm post into the pusher post (keys 10 and 11).

10. Install the upper casing (key 2) and secure it to the lower casing (key 1) with the eight hex head screws (key 23). Tighten the hex head screws evenly using a crisscross pattern to avoid placing an uneven

strain on the regulator. Tighten the screws to a nal bolt torque of 10 to 13 foot-pounds / 13 to 17 N•m

to avoid crushing the diaphragm.

CAUTION

In step 11, the spring seat (key 4) is under spring pressure. Use constant hand pressure to hold the spring down when installing the hex nuts (key 5), see Figure 5.

11. Install the closing spring (key 6) and the spring seat (key 4). Push and hold down on the spring seat, cocking it to one side until the seat catches onto the threads of the diaphragm post (key 10). Then, pull up on the diaphragm post allowing access to the post threads so that the two adjusting hex nuts (key 5) can be installed. Install the adjusting hex nuts as shown in Figure 5. The closing spring must be adjusted down to a depth of 1/2-inch / 13 mm from the top of the upper case opening to the top of the spring seat. When tightening the two hex nuts, use care not to rotate the diaphragm post, which may damage the post.

12. Lightly lubricate the O-ring (key 9) on the closing cap and reinstall the closing cap (key 3).

WARNING

The wire seal and warning tag (keys 68 and 69) contain important safety information, make sure they are attached when maintenance is completed.

When assembling the diaphragm assembly (keys 8, 80 and 81), lubricate the actuator diaphragm post (key 10) threads.
