Quarter Turn

Morin EHP

EHP series - Electrically powered spring return actuator for quarter-turn valves and dampers. Spring ending torques from 1,200 to 52,800 lb.in.

Features & Benefits:

  • Electrically powered, 115 or 230 V AC, single phase, 60 Hz.
  • Spring return, fail to safe position on loss of main power supply
  • Thermally protected motor
  • Standard Beacon position indicator
  • 2 SPDT switches for end of travel indication, dry contacts
  • Ductile iron housing provides long product life with durable, cost effective operation
  • Bi-directional travel stops provide accurate valve rotation adjustment
  • Tectyl-coated springs need no special tools to be disarmed safety and easily, reducing down time
  • Easily removable housing cover provides easy access for yoke mechanism inspection
  • High strength alloy steel or 17-4PH stainless steel output shaft transmits torque without fatigue
  • Sintered bronze or PTFE composite output shaft bearings eliminate side loading of valve stem to maximize stem packing performance
  • Strong, corrosion-resistant chrome-plated steel piston rod for enduring high-cycle applications
  • Sintered bronze piston rod bushings provide low-friction support and precise alignment to increase efficiency, reduce maintenance and extend actuator life
  • Heat-treated stainless steel thrust pin and rollers transfer piston force to yoke to reduce friction, for longer life and more efficient torque transmission
  • PTFE guide bands ensure low-friction piston guidance protecting cylinder walls from potential scoring and extending seal performance with a continuous cylinder wiping action

Designed specifically for automating any quarter-turn ball, plug or butterfly valve where Emergency shutdown (ESD) on loss of electrical power is required.
