ASCO H137CQ32F1F26V16 Shut-Off Gas Valve

Asco Shut-Off Gas Valve, 120 V, Cast Iron Body, -40 to 175 deg F, 17.81 in W x 34.88 in H

• The H137 is a two-way, normally closed, safety shut-off valve providing trouble-free, electro hydraulic on-off control of combustion
• The self-contained hydramotor actuator is a powerful, pull-type hydraulic ram providing output force of 1400 lb to fully open the valve
• Upon current interruption, dual redundant relief valves dump hydraulic pressure, closing the valve in 1 sec
• The Hydramotor consists of a motor/pump unit immersed in oil, reducing wear and provides highly reliable operation
• The H137 is a cast iron bodied valve with nitride seat and aluminum trim
• Pulling force from the hydramotor actuator moves a lever against spring and gas pressure to open the soft-seated flap, allowing straight-through gas flow
• A simple, 2-wire circuit controls the motorized valve
• H137 is equipped with one standard SPDT switch which actuates at the fully-open (Energized) Position and valve seal over travel interlock switch which can be wired into the start-up or pre-ignition interlock circuit to permit supervision of the valve closed position
• Body class-cast iron, 2-3 in #250 screw, 4-6 in #125 flanges
• Pipe taps-1/4 in upstream and downstream taps for routine leak testing
• Auxiliary switch-Integral SPDT switch, 15 A at 120 V actuates at full open position of actuator stroke (not adjustable), upto 2-adjustable yoke-mounted witches may be added
• Proof of closure switch-integral factory set, non-field adjustable SPDT switch, 1/4 hp at 120 V
• 50000 cu-ft/hr nominal capacity
