ASCO AH2E112S5

Proof of Closure Watertight Fast Opening Hydramotor Actuator, Auxiliary Switch, Damper Shaft \& Arm (110/120V)

The AH2E Hydramotors are push-type, self-contained, electrohydraulic linear actuators which extend when powered and retract by spring force upon power interruption.

AH2E 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 AH2E Hydramotor/V710 gas valve combination provides 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.

Installation:

AH2E Hydramotor mounts in any position directly to a V710 valve with 3 set screws.

Electrical:

• Proof of Closure Switch: (Optional) A factory set, non-field adjustable SPDT switch. 1800VA max. connected load (e.g. one 15A max. load @ 24V or 120V; one 7.5A max. load at 240V).
• Auxiliary Switches: (Optional) One or two integral SPDT switches; field adjustable to actuate at any position of stroke. 1800 VA max. connected load (e.g. one 15A max. load @ 24V or 120V; one 7.5A max. load at 240V).

Damper Arm Rating:
