V4055A,B,D,E
INSTALLATION
INSTALL VALVE
The actuator is mounted directly on the valve bonnet
after the valve is installed in the gas supply line. Refer to the
instructions packed with the gas valve for installation details. When installing the valve, assure that:
1. Sufficient clearance is left for installation and service
of the actuator.
2. Ambient temperatures at the valve location will re-
main within -40° to 150°F [-40°C to 66°C] or -10°F to 158°F
[-23°C to 70°C] (see Specifications section).
3. Position of the valve permits hookup to the damper if
one is controlled.
INSTALL ACCESSORY SWITCHES (IF NEEDED)
A spdt auxiliary switch may be installed to operate a
load up to 1/2 hp [0.37 kW]. The switch may be adjusted to
operate at any point in the valve stroke.
A proof-of-closure switch may also be installed on any
V4055 actuator to provide a valve seal overtravel interlock
when used with a V5055C or E valve (with double seal).
The spdt proof-of-closure switch is installed to make or
break a circuit when the valve is in the closed position. The
switch is not adjustable.
NOTE: Mark the actuator or valve to indicate any changes
made.
4. Insert the proof-of-closure switch in the position shown
in Fig. 2. The switch mounts against the side of the actuator
housing. The mounting holes are spaced to mount the switch
only in the correct position. Fasten with two screws through
the actuator base. The proof-of-closure switch is not adjustable.
5. If only one switch is used, install the narrow barrier
included with the switch in the unused space.
6. Mount the actuator before making wiring connections
and adjustments to the auxiliary switch.
MOUNT ACTUATOR ON VALVE
Check the final position of the valve body to be sure that
the actuator will be in the proper position when mounted on
the valve. This is especially important if the actuator is used
to drive a damper.
If two smaller sized valves are mounted very closely
together, as in an Industrial Risk Insurers type valve train, it
may be necessary to mount the actuator off center to
provide adequate clearance.
Slip the bottom collar of the actuator over the valve
bonnet assembly. Rotate the actuator to the desired position and use a 5/32 inch Allen wrench to securely tighten
the two set screws. (50 to 60 lb/in [5.7 to 6.8 Nm]).
Connect the damper linkage, if used. Refer to the instructions packed with the damper arm.

To install the switches, proceed as follows:
1. Remove the actuator faceplate (two screws).
2. Remove the sliver-colored barrier to expose the actua-
tor stem.
3. Insert the auxiliary switch in the position indicated in
Fig. 2. Fasten with two screws through the actuator base.
TO REPLACE A V4034 ACTUATOR ON A V5034
VALVE
IMPORTANT: When replacing a standard (26 sec) V4034
actuator on a V5034 Valve, check the main burner
flame-establishing period (MFEP) of the burner primary safety control. If the MFEP is 10 sec, you must
use a fast-opening (13 sec) V4055 Actuator on the
older V5034 Valve.
The initial action of the V4055 Actuator does not
immediately open the V5034 Valve because of a difference in stroke length. The pilot may be shut off before
the main burner flame is established. The fast-opening
V4055 Actuator will open the V5034 Valve fast enough
to establish the main burner flame within the ten
second flame-establishing period.
If it is desirable to maintain the slower opening
characteristic of the standard V4034 Actuator, both
the V4034 Actuator and V5034 Valve should be replaced. Use a standard V4055 Actuator on a V5055
Valve.
Select the correct adapter, depending on whether the
V5034 has a long or short stem (Fig. 3). Fasten the adapter
to the V5034 Valve bonnet, and then mount the actuator on
the adapter. Follow the instructions for mounting the actuator on the valve.
If the V4034 being replaced is equipped with a heater,
there will be a low limit control connected in series with the
V4034 power supply to prevent actuator operation below
25°F [-4°C]. There will also be a constant source of the line
voltage power to the heater and its control thermostat.

IMPORTANT: The V5055 Valve is designed to provide
control of gaseous fuel (natural and LP gas) flow in
applications in which there is minimal exposure to
water. V5055 Valves used in maritime, beverage, food
processing, outdoor and other installations in which
occasional exposure to water is experienced may be
subject to valve stem and spring corrosion. The presence of corrosion decreases the operating life of the
valve. V5055 Valves used in such installations should
be inspected at least annually and should have the
valve bonnets replaced if corrosion is noted.
A V4055 Valve Actuator with a NEMA 4 rating is also
recommended for such installations. The water-tight
design of the NEMA 4 rated V4055 Actuator prevents
water from entering the V4055 valve stem and spring
chamber through the actuator. Under certain conditions, some water may be retained by the external
upper portion of the valve body. The retained water is
effectively excluded from the valve stem and spring
chamber by a functional seal that is incorporated into
the NEMA 4 rated actuator.
WHEN INSTALLING THIS PRODUCT…
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced, flame safeguard control technician.
4. After installation is complete, check out product
operations as provided in these instructions.
8. Use the valve size at the intersection of the horizontal
and vertical lines. If the intersection is between valve sizes,
use the next higher size to the right.
TO SIZE TWO IDENTICAL VALVES PIPED IN
SERIES
1. Find the cf/h for the type of gas used.
2. Consider both valves as one unit. Determine the total
maximum pressure drop across the unit.
3. Find the pressure drop across the first valve by assuming it to be 45 percent of the total pressure drop.
4. Find the valve size from Fig. 1.
5. The second valve will be the same size as the first
valve.
Installation
CA UTION
1. Turn off gas supply before starting installation.
2. Disconnect power supply for valve actuator
before beginning installation to prevent electrical shock and equipment damage.
3. Be sure the valve is installed so the arrow on the
valve points in the direction of gas flow. (Gas
pressure helps to close the valve.)
LOCATION
Install the valve in the gas supply line downstream from
the pressure regulator. The valve and actuator may be
mounted in any position that allows sufficient clearance for
installation and for repair or replacement.
1. The valve position indicators should be easily visible
with the valve and actuator in the final position.
2. The final position of the valve and actuator must allow
for damper linkage, if used.
IMPORTANT: Allow room for turning the valve body
(actuator not attached) onto the gas piping. Swing
dimensions, measured from the center of the pipe are:
3/4 through 1-1/2 in. valves: 4 in. (101.6 mm).
2 through 3 in. valves: 5 in. (127.0 mm).
4 in. valves: 7 in. (177.8 mm).
MOUNTING (Figs. 4 through 6)
WARNING
If flow is not in the direction of the arrow on the
valve body, the valve may not shut off.

8. Use two threaded companion flanges, two gaskets
(included with valve), and 16 bolts (with washers and nuts)
for mounting a 4 in.-V5055 Valve. Mount a threaded flange
and gasket on each end of the valve as shown in Fig. 6. Then
screw the pipes into the threaded flanges. Apply dope sparingly, and use wrenches and vises properly as shown in Fig.
4 and 5.
9. Make sure the power supply is disconnected from the
valve actuator. Then mount the actuator on the valve body
and complete the electrical and linkage connections following the instructions packed with the actuator.

3. Remove the protective caps from the ends of the valve.
Do not attach the valve actuator until the valve body installation is complete.
4. Apply good quality pipe dope resistant to action of LP
gas, putting a moderate amount on the male threads only.
Use dope sparingly; if pipe dope lodges on the valve seat, it
will prevent proper closure.
5. Install valve with the gas flow in the direction indicated by the arrow on the casting.
6. Apply a parallel jaw wrench only to the flat next to the
pipe being inserted (Fig. 5). A wrench applied to the valve
body itself, or to the end farthest from the pipe being inserted,
may distort the casting, causing a malfunction. Do not use the
valve for a lever.
7. Be sure the gas flow is in the same direction as the
arrow on the bottom of the valve body.

OPERATION
A V5055 Industrial Gas Valve is operated by a V4055,
V4062, or V9055 Fluid Power Gas Valve Actuator. The
valve opens when the actuator is energized, and closes
when power is removed. When closed, the valve seals off
against the rated close-off pressure with no power applied.
For further information, refer to the Instructions for the
actuator.

OPERATION AND CHECKOUT • SERVICE INFORMATION
VALVE LEAK TEST (Fig. 7)
This is a test for checking the closure tightness of a gas
safety shutoff valve. It should be performed by qualified
personnel during the initial startup of a burner system, or
whenever the valve or valve bonnet is replaced (see Service
Information section). It is recommended that this test also
be included in the scheduled inspection and maintenance
procedures. For a periodic inspection test, follow steps 1,
3, 4, 5, 8, 9, 10, 12, 13, 16, and 17.
1. De-energize the control system to assure that there is
no power to the safety shutoff valve (C) shown in Fig. 7.
2. Close the upstream manual gas cock (A).
3. Make sure the manual test petcock (F) is closed in the
leak test tap assembly (D).
4. Remove the leak test tap plug and connect the test
apparatus to the Leak Tap (D).
5. Close the downstream manual gas cock (E).
6. Open the upstream manual gas cock (A).
7. Run the safety shutoff valve (C) to its fully open
position (through the safety system); then immediately deenergize the system to close the valve.
8. Immerse a 1/4 in. tube vertically 1/2 in. (12.7 mm) into
a jar of water.
9. Slowly open the test petcock (F).
10. When the rate of bubbles coming through the water
stabilizes, count the number of bubbles appearing during a
ten-second period. Each bubble appearing during a tensecond period represents a flow rate of approximately
0.001 cfh.
To meet U.S. requirements, leakage must not exceed the
following values:

Based on air at standard conditions, test pressures provided by ANSI Z21.21, Section 2.4.2 and a maximum of
235 cc/hr per inch of seal-off diameter. Seal-off diameter
is not to be confused with pipe size.
NOTE: For international leak test requirements, contact the
office of the appropriate approval agency.
AFTER THE TEST:
11. Close the upstream manual gas cock (A).
12. Close the test petcock (F), remove the test apparatus,
and replace the leak test tap plug (D).
13. Open the upstream manual gas cock (A) and energize
the safety shutoff valve (C).
14. Test with soap bubbles to assure that there is no leak at
the test tap (D).
15. De-energize the safety shutoff valve (C).
16. Open the downstream manual gas cock (E).
17. Restore the system to normal operation. If two safety
shutoff valves are utilized, each 550V valve is to be checked
for tightness of closure.

SERVICE INFORMATION
For part numbers, refer to Replacement Parts in the
Specifications section. Complete instructions for replacing
the bonnet assembly are included with the replacement
part.
REPLACEMENT OF SEALS (Fig. 8 or 9)
When removing the bonnet to inspect and clean the
valve, install new seals (see Replacement Parts in Specifications section). Coat the new seals with the grease provided, and position them in the valve body as shown in
Fig. 8 or 9.
Fig. 8—Proper positions of valve and bonnet
seals in 3/4 through 3 in. valves.
BONNET SEAL
Failure to properly position and seat the seals in the
valve body may result in a hazardous gas leak.
After the new bonnet assembly is installed, or the bonnet
is removed for any reason, check for gas leakage around the
bonnet seal. Turn on the gas at the manual valve. Paint the
seal area with a rich soap and water solution. Bubbles
indicate a gas leak. If a leak is detected, check to see that the
bonnet screws are tight. If necessary, turn off the gas again
and remove the bonnet to be sure the seals are properly
seated.
