Overview of Primary Product

V5055A-F INDUSTRIAL GAS VALVES
3 60-2307—16
a
Maximum operating pressure differential. Once open, the valve and actuator operate correctly against this pressure at 85% of
rated voltage.
b
Maximum opening pressure. Actuator opens valve against this pressure at 85% of rated voltage.
c
Maximum close-off pressure. Maximum allowable pressure drop across fully closed valve prevents seal leakage (independent of
75 psi valve body rating).
d
V5055F available in 1 in., 1-1/2 in., and 2-in. sizes only.
Models: See Table 3.
Type of Gas: Natural or liquefied petroleum (LP) only.
Pipe Size: 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3, and 4 in.
(only V5055A,B,C available in 4 in. size).
Pipe Threads: NPT or BSP-PL Threads (equivalent to ISO
R7 and DIN 2999). Available on inlet and outlet of 3/4 to 3 inch
valves. Four inch valves have flange connections.
Pressure Ratings: See Table 2.
Valve Body Rating: 75 psi (5.2 bar).
Valve Capacities: At 1 in. (2.5 mbar) pressure drop; based on
gas with specific gravity of 0.64.
Upstream Tapping and Plug: 1 /4 in. NPT or BSP-PL
is standard.
Downstream Tapping and Plug:
1/4 in. NPT on most domestic models.
1/8 in. NPT on V5055C1182.
Ambient Operating Temperature Rating:
-40°F to 150°F (-40°C to 66°C); -40°F to 125°F
(-40°C to 52°C) when used with V9055.
Table 4. Valve Rated Capacity.
Material: Die-cast aluminum.
Mounting: Mounts directly in the gas supply line.
Dimensions: See Fig. 2 and 3.
Weight:
3/4, 1, 1-1/4, 1-1/2, in. valve: 4 lb. (1.8 kg).
2 in. valve: 8 lb. (3.6 kg).
2-1/2, 3 in. valve: 11 lb. (5.0 kg).
4 in. valve: 28 lb. (12.7 kg).

Model Number Features
V5055A Industrial Gas Valve for On-Off service.
V5055B Industrial Gas Valve with characterized
guide for slow opening, HI-LO-OFF, or
modulating service.
V5055C Same as V5055A but incorporates a double
seal. Used with the V4055D Actuator to a
provide proof-of-closure switch and a valve
seal overtravel interlock.
V5055D Same as V5055A but for high pressure
applications.
V5055E Same as V5055C but for high pressure
applications.
V5055F Same as V5055E but meets the intent of
EN161 leakage requirements.
