Fuel Gas Valves H137

The H137 Fuel Gas Valve is a two-way, normally closed, safety shutoff valve providing trouble free, electrohydraulic, on-off control of combustion gas for boilers, industrial furnaces, dryers, dehydrators, large conversion burners, air heaters and similar applications.

The self contained actuator is a powerful, pull-type, hydraulic ram providing output force of 1400 pounds to fully open the valve. Upon current interruption, dual redundant relief valves dump hydraulic pressure, closing the valve in one second. The H137 consists of a motor/pump unit immersed in oil, reducing wear and the need for service.

Fuel Gas Valves H137

The H137 is a cast iron-bodied valve with Nitrile seat and aluminium trim. Pulling force from the actuator moves a lever (providing mechanical advantage) against spring and gas pressure to open the soft seated flap, allowing straight-through gas flow.

Each H137 is equipped with one standard SPDT switch, which actuates at the fully-open (energized) position. The H137 Valve is equipped with a valve seal overtravel interlock switch which can be wired into the startup or pre-ignition interlock circuit to permit supervision of the valve’s closed position (FM Proof of Closure).
