This is an On-Off Fast Opening (14 seconds Max) Watertight Hydramotor model, with Proof Of Closure. The AH2 Hydramotors are push-type, self-contained, electrohydraulic linear actuators which extend when powered and retract by spring force upon power interruption. AH2 Hydramotors provide a fast spring return shutoff time of one second or less. When the actuator is mounted to a V710 gas valve, position indicators on both sides of the actuator show the open or closed position of the valve. The AH2 Hydramotor/V710 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. On-Off Fast Opening (14 seconds Max) (Watertight) Includes: Damper shaft & arm Installation AH2E Hydramotor mounts in any position directly to a V710 valve with 3 set screws. Damper Arm Rating Drives damper in one direction only. 20 lb. max. at 2.85° radius at 20°F to 150°F and 10 lb. max. at -40°F to 20°F.
