ASCO H137 Series HydraMotor Valves

Brand: ASCO
Request Information
The ASCO H137 Series is a cast-iron bodied safety shutoff valve with electrohydraulic actuator for on-off control of combustion gas.

It is designed for boilers, industrial furnaces, dryers, dehydrators, large conversion burners, air heaters, and similar applications.

The self-contained Hydramotor actuator is a powerful, pull-type hydraulic ram providing output force of 1,400 pounds to fully open the valve.

Upon current interruption, dual-redundant relief valves dump hydraulic pressure, closing the valve in 1 second or less.
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.
