ASCO AH4E112S Hydramotor Actuator

The ASCO Series AH4E low high off hydramotor is a push-type, self-contained, electrohydraulic linear actuator featuring dual internal control valves for repeatable positioning. The low fire position is field adjustable to any position between 15% and 100% of stroke. When power is applied, the actuator shaft travels to the low fire position. After an external switch completes the low fire controller circuit, the shaft continues to the high fire setting. Opening the external switch returns the shaft to the low fire setting and power interruption fully closes the valve in 1 s or less from any position. The AH4E low high off hydramotor/V710(B) gas valve combination provides main line control for boiler, furnace and oven applications plus industrial and commercial burners.
