V5055A-F INDUSTRIAL GAS VALVES

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.
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.
OPERATION AND CHECKOUT
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.

WARNING
Explosion Hazard.
Can cause serious injury, death or property
damage.
Do not allow fuel to accumulate in the combustion
chamber. If fuel is allowed to enter the chamber
for longer than a few seconds without igniting, an
explosive mixture could result.
