General Description
The AH4E Hydramotors are three-position push-type, self-
contained, electrohydraulic linear actuators featuring dual
internal control valves for repeatable positioning. The low-
fire 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.
