Morin Hydraulic Valve Actuator Series HP

Technical Data Supply pressure: Up to 2,250 psig Supply medium: Any pneumatic or hydraulic fluid compatible with materials of construction. Temperature Rating Standard: -20°F to 210°F Optional: -65°F to 300°F Angular rotation: 90 degrees ±8 degrees

  • 2,250 psig Operating Pressure Rating
  • Direct Gas/Hydraulic Actuators
  • Ductile Iron/Stainless Steel Quarter-turn
  • Double Acting and Spring Return Models
  • Output Torques to 1,091,564 lb. in.

Designed for “on-off” or modulating control of any quarter-turn ball, butterfly, rotary plug, or damper-style valve applications. For use in chemical processing, food & beverage, iron & steel, off-shore marine, pharmaceutical, power, oil & gas, pulp & paper, and textile industries.

Features & Benefits:

  • High-pressure construction eliminates undesirable regulators and relief valves for supply pressures.
  • Hydraulic dampening provides smooth “open-close” operation to prevent detrimental valve slamming.
  • Ductile iron housing provides long product life with durable, cost-effective operation.
  • Output shaft made of high-strength alloy steel transmits torque without fatigue.
  • Sintered bronze bushings or Teflon® composite bearings on the output shaft eliminate sideloading of the valve stem to maximize stem packing performance.
  • Chrome-plated steel piston rod provides strength and corrosion resistance for enduring high-cycle applications.
  • Sintered bronze piston rod bushings provide low-friction support and precise alignment of the piston rod to increase efficiency, reduce maintenance, and extend actuator life.
  • Heat-treated stainless steel thrust pins and rollers transfer piston force to 17-4PH stainless steel or ductile iron yoke by rolling to reduce friction, for longer life and more efficient torque transmission.
  • Teflon® guide bands ensure low-friction piston guidance during operation to protect cylinder walls from potential scoring and extend seal performance with a continuous cylinder wiping action.
  • Bi-directional travel stops provide accurate valve rotation adjustment.
  • ISO 5211 mounting promotes easier valve adaption by utilizing internationally recognized mounting patterns.
  • The NAMUR drive slot on the output shaft enables accessory-driven components to maintain a compact, low-profile assembly.
  • Tectyl-coated springs can be disarmed without special tools to safely and easily disassemble the actuator in the field, reducing downtime and providing a “man-safe” spring.
  • Easily removable housing cover provides effortless access for internal inspection.
