Hydramotor valves are designed for main line gas control. These valves typically operate from a single contact on-off type limit control to provide tight shut-off of dry natural, mixed, manufactured or LP gases. It consists primarily of two components: the actuator and the valve. Actuator is easily rotatable for best positioning of damper and electrical terminals. The valve is a globe type, 2-way normally closed, die-cast body and bonnet with a soft synthetic seat disc.
