Description
The AH4E Hydramotors are three-position push-type, selfcontained, electrohydraulic linear actuators featuring dual internal control valves for repeatable positioning. The lowfire position is factory set at the stroke midpoint, but can be 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 on 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 one second or less from any position.

The AH4E Hydramotor/V710(B) 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.

Installation:
AH4E Hydramotor mounts in any position directly to a V710 valve with 3 set screws.

Electrical:
  • Proof of Closure Switch (POC) : (Optional) A factory set, non-field adjustable SPDT switch. 1800VA max. connected load (e.g. 15A max. load @ 120V; 7.5A max. load at 240V).
  • Auxiliary Switches: (Optional) One integral SPDT switch; field adjustable to actuate at any position of stroke. 1800 VA max. connected load (e.g. 15A max. load @ 120V; 7.5A max. load at 240V). (Note: Not available if optional POC switch is ordered)
