AUTOMATIC SAFETY SHUTOFF VALVES
70-8509—01 2
V5055/V5097 Industrial Gas Valves
• V5055 / V5097 single-seated, normally closed valves are
suitable for service requiring tight shutoff.
• Can be used with natural or liquefied petroleum (LP)
gases.
• V5055A / V5097A,C,D,E Valves are for On-Off service.
• V5055 / V5097B Valve has a characterized guide to
provide slow opening, Hi-Lo-Off, or Modulating service.
• V5055 / V5097C,E Valves have two seals and when used
with the V4055D,E Actuators, the combination provides a
proof-of-closure switch and valve seal overtravel interlock.
• V5055 / V5097D,E Valves are for high pressure
applications.
• V5055 models feature threaded connections for seven
pipe sizes from 3/4- to 3-inch NPT (or parallel BSP);
V5055A,B,C are also available in a 4-inch size with flange
connections.
• Standard with 1/4-inch upstream and downstream tapping
with plug.
• V5097 models are available in small-body size covering
3/4” to 2” pipe size and large-body size covering 2” to 3”
size.
Fluid Power GasValve Actuators
• Rated for final safety shutoff service when used with V5055
/ V5097 Valves.
• V4055 Actuators are for On-Off service, V4062 Actuators
are for Hi-Lo-Off service, and V9055 Actuators are for
Modulating service.
• V4055D,E, V4062D, and V9055D Actuators have a proof-
of-closure switch to provide valve seal overtravel interlock
when used on a V5055 / V5097C,E Valve with a double
seal.
• V4055B,E Actuators are for high pressure applications.
• Maximum closing time is one second, which meets
approval body requirements.
• Red OPEN indicator attached to the actuator stem will
show if the valve is even slightly open; yellow SHUT
indicator on the valve stem will show only when the gas
valve is fully closed .
• Standard enclosure meets NEMA 1 general purpose
requirements; optional enclosure meets NEMA 4
weatherproof requirements.
• Optional damper shaft available with or without spring
return; shaft extends out both sides and rides in Teflonlike,
Delrin bushings.
• Uses standard damper crank arm, which is readily
available from wholesalers.
• Optional, field-adjustable, spdt auxiliary switch is available.
• Low-fire adjustment on V4062 and V9055 Actuators is
internal to minimize tampering.
• V9055 Actuator has internal, 24 volt transformer for line
voltage connections and a field addable kit is available to
provide V9055 acceptance of a 4 to 20 mA dc signal.
Table 2. Pressure Ratings of Valve-Actuator Combinations
a
Max Operating Pressure Differential (UL) or Max Operating Pressure (CSA); maximum allowable pressure drop from inlet to
outlet for proper operation .
b
Max Rated Pressure (UL) or Max Close-off Pressure (CSA) ; maximum pressure that the valve can be exposed to without leak-
age or damage to the valve.
c
Applies for small-body V5097 valves 3/4” up to 2” pipe size.
d
Applies for large-body V5097 valves 2” up to 3” pipe size.
e
V5055A, B, C only.
