Morin Series HP Actuator

2,250 psig Operating Pressure Rating
Direct Gas/Hydraulic Actuators
Ductile Iron/Stainless Steel Quarter-turn
Double Acting and Spring Return Models
Features and 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 or 17-4PH stainless transmits
torque without fatigue.
• Sintered bronze bushings or Teflon®
composite bearings on output shaft
eliminate sideloading 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 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.
• NAMUR 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.

General Applications
Designed specifically for automating
quarter-turn pipeline valves, providing
control for any quarter-turn ball, plug
or butterfly valve application.
