 V5055 INDUSTRIAL GAS VALVES
• V5055 single-seated, normally closed valves are suitable
for service requiring tight shutoff.
• Can be used with natural or liquefied petroleum (LP)
gases.
• V5055A,C,D,E Valves are for On-Off service.
• V5055B Valve has a characterized guide to provide slow
opening, Hi-Lo-Off, or Modulating service.
• V5055C,E Valves have two seals and when used with the
V4055D,E Actuators, the combination provides a proofof-
closure switch and valve seal overtravel interlock.
• V5055D,E Valves are for high pressure applications.
• 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.
• Valve body rating of 75 psi (517.1 kPa).
FLUID POWER GAS VALVE ACTUATORS
• Rated for final safety shutoff service when used with
V5055 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 proofof-
closure switch to provide valve seal overtravel interlock
when used on a V5055C,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.
