Product Description
Asco AHD112A Hydramotor Gas Valve
Part #: AHD112A
The AH2D Hydramotors are push-type, self-contained, electrohydraulic linear actuators which extend when pow- ered and retract by spring force upon power interruption.
AH2D Hydramotors provide a fast spring return shutoff time of one second or less. When the actuator is mounted to a V710(A) gas valve, position indicators on both sides of the actuator show the open or closed position of the valve.
The AH2D Hydramotor/V710(A) gas valve combination provides reliable main line gas control for a wide range of applications, including boilers, furnaces, ovens and all types of industrial and commercial burners. It is available in either a slow or fast opening construction.
