ASCO AH4E112A4 110/120V Watertight Hydramotor Actuator with Damper Arm

The ASCO AH4E112A4 is a watertight, fast-opening, three-position push-type electrohydraulic linear Hydramotor actuator equipped with a damper shaft and arm. Featuring dual internal control valves for highly repeatable positioning, this actuator is designed to provide reliable main line gas control in boilers, furnaces, ovens, and industrial burners when paired with a V710(B) gas valve. The low-fire position is factory set at the stroke midpoint but can be easily field-adjusted between 15% and 100% of the stroke length. For maximum safety, any power interruption will fully close the valve in one second or less from any position. Constructed from durable aluminum, this unit safely mounts in any position directly to a V710 valve.
