ASCO AH4E HydraMotor Actuator

Brand: ASCO
The ASCO 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 second 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.
Features
  • Broad ambient temperature range suitable for hot (150° F/66° C) or frigid (-40° F/-40° C) environments.
  • Slow- or fast-opening constructions make it suitable for a variety of applications.
  • Type 1 General Purpose enclosure standard, optional Type 4 Watertight enclosure available for outdoor or indoor wash down installations.
  • Rugged construction ensures high reliability and durability.
  • Visual indication of valve open & closed position is standard.
  • Optional electrical interlock proof of closure switch is available.
  • Mountable in any position for installation flexibility.
  • UL Listed, FM Approved, CSA Certified.
