Hydramotor Fuel Gas Valves H137
The Hydramotor H137 is a cast iron-bodied valve with Nitrile seat and aluminium trim. Pulling force from the Hydramotor actuator moves a lever (providing mechanical advantage) against spring and gas pressure to open the soft seated flap, allowing straight-through gas flow.
Each Hydramotor 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).
Almost all types of Hydramotor Valves are available at Controls Supply Chain. If you don’t know what type of valve is suitable for your configuration please don’t hesitate to contact the sales department of Controls Supply Chain at email@example.com.
