1 MORIN series - Ductile iron w/ stainless steel cylinders C series - Ductile iron w/ carbon steel cylinders Spring return and double acting actuators Quarter-turn output torques to Nm Features and benefits Ductile iron housing, piston and end caps provide 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 PTF composite 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 or ductile iron yoke by rolling to reduce friction, for longer life and more efficient torque transmission. PTF 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. i-directional travel stops provide accurate valve rotation adjustment. ISO 5211 mounting pattern promotes easier valve adaptation by utilizing internationally recognized standards. oth series and C have been certified to SIL 3 ratings. Series C Series ctuators are rated IP66. NMUR drive slot on output shaft enables accessory-driven components to maintain a compact assembly and eliminates the need for couplings. 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. asily removable housing cover provides effortless access for internal inspection of yoke mechanism.

2 Morin has a rugged heart Morin scotch yoke The heart of any scotch yoke actuator is the yoke. Morin uses either 17-4PH or ductile iron for this critical area as standard. The yoke is the mechanism used to convert linear force to torque. The yoke is critical to actuator performance. It must be rugged, yet precisely machined to give long life at high efficiency. Morin understands this and ensures that all our yoke designs meet this test. Principles of construction Using high quality materials of construction and modern rugged design concepts Morin becomes the standard for low cost valve actuation while providing high quality performance. The actuator housings are all machined from ductile iron castings. This produces a rugged, low cost product through reduced machining time and by eliminating wasteful excess material. ny components that rotate or slide during operation, such as the high strength output shaft, chrome-plated piston rod, stainless steel thrust pin or the ductile iron piston, are all supported by replaceable friction reducing bearings. i-directional travel stops djustable stops on each end cap provide the flexibility of accurate valve rotation positioning at the end of the open and close stroke. oth stops are located on the cylinder centerline, the optimal position to maximize travel adjustment and eliminate any detrimental side loading on the travel stops. djustable from 82 to 98. Spring designed for safety ll spring return models incorporate a man safe spring design that allows the actuator to be safely assembled and disassembled in the field without the need for special tools. The integral tie rods are bored and tapped to provide a means of loading and unloading the spring in a safe and convenient manner. Morin understands actuator design Morin understands that the most efficient design for one torque range is not the most efficient for another. Morin uses the standard scotch yoke design for lower torque ranges and a guide bar design for the higher torque ranges. This gives a rugged design with economic cost.

4 Symmetrical and canted yokes It s about fitting the torque curve of the actuator to the valve... It s about lower cost, lighter weight, smaller actuators... It s about CHOIC... Symmetric Symmetrical yoke design offers the standard torque curve seen most often in relation to scotch yoke actuators. It offers the increased torque advantage at both ends of the 90 stroke as shown on the blue curve below. This torque curve covers most quarter-turn applications. Canted Canted yoke design moves the torque curve to where it s needed most, gaining as much as 35% more break and reseat torque for the same size actuator. The canted yoke curve is shown in red below. Canted yoke actuators allow selection of smaller, lighter, and less expensive actuator packages Torque output (percent) Symmetric Canted 0 ctuator rotation (degrees) 90 Pentair reserves the right to change the contents without notice page 4
