Keystone Hydraulic Actuators Morin Figure B-HP actuator

1,500 psig operating pressure rating Direct gas/hydraulic actuators Ductile iron/stainless steel quarter-turn Double acting and spring return models

Features & Benefits:

• High pressure construction eliminates undesirable regulators and relief valves for supply pressures up to 1,500 psig.
• Hydraulic dampening provides smooth “open-close” operation to prevent detrimental valve slamming.
• Ductile iron housing provides long product life with durable, cost effective operation.
• Cylinders of 316 stainless steel provide unrivaled corrosion resistance.
• Output shaft made of high strength alloy steel transmits torque without
• Sintered bronze bushings or sealed needle bearings on output shaft eliminate side loading of 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 pin and rollers transfer piston force to
  17-4PH stainless steel yoke by rolling to reduce friction, for longer life and more efficient torque transmission.
• PTFE 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 adaptation by utilizing internationally recognized mounting patterns.
• Drive slot on 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 down time and providing a “man-safe” spring.
• Easily removable housing cover provides effortless access for internal inspection.
• Dry piston seal consists of a one piece graphite filled TFE ring with an O-ring expander. Seal is self lubricating and performs well in direct gas and hydraulic service.
