Stainless Steel Quarter-turn Spring Return

Morin Figure 79B Actuator

Ductile Iron/Stainless Steel Quarter-turn Spring Return and Double Acting Actuators Output Torques to 115,000 lb.in.

Features and Benefits • Ductile iron housing, piston and end caps provide 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 fatigue. • 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. • Teflon® guide bands ensure lowfriction 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.

• 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 of yoke mechanism.

• ISO 5211 mounting pattern promotes easier valve adaption by utilizing internationally recognized standards. • Drive slot on output shaft enables accessory-driven components to maintain a compact, low profile assembly and eliminates the need for couplings.

ACTUATOR FAILURE!

Materials of Construction Item

The most common cause of actuator failure is wear on the seals. If condensed water from air lines collects in an aluminum or steel cylinder, pitting will occur. Pitting will eventually destroy a seal and cause piston “blow by” and ultimate failure. Teflon® piston bearings come in contact with 316 stainless steel cylinders, a standard on all Morin actuators. Lubrication is never required. All moving parts are supported with sintered bronze bushings or sealed needle bearings. Structural members including yoke, thrust pin and roller bearings are made from heat treated stainless steel. The Morin Actuator is designed to perform in the most demanding corrosive environments. This includes a “nice, clean, noncorrosive” plant with water in its air lines.

Principles of Construction Using ductile iron and stainless steel, the 79B becomes the standard for low cost valve actuation while providing high quality performance. The actuator housing, end caps, adaptors and piston are all machined from ductile iron castings. This produces a rugged, low cost product through reduced machining time and by eliminating wasteful excess material. Cylinders of 316 stainless steel provide the ultimate in corrosion resistance and increased piston seal performance while reducing maintenance costs. Any components that rotate or slide during operation, such as the high strength alloy steel plated output shaft, chrome-plated piston rod, stainless steel thrust pin or the ductile iron piston, are all supported by replaceable friction reducing bearings.

Spring Designed for Safety

Position Indicator and Pointer

All 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.

On Models 006 through 100, the ‘open-shut-open’ indicator plate allows the use of the same indicator and pointer when the failure mode needs to be reversed. When changing from ‘fail-close’ to ‘failopen’ on spring return models, simply mount the stainless steel position indicator plate and pointer on the opposite side of the actuator. The position indicator plate and pointer can be mounted parallel or perpendicular to the actuator centerline.

ISO 5211 Mounting To provide the greatest flexibility for valve adaptation, each model has a mounting pattern designed in accordance with International Organization for Standardization (ISO) requirements.

Bi-directional Travel Stops Adjustable stops on each end cap provide the flexibility of accurate valve rotation positioning at the end of the ‘open’ and ‘close’ stroke. Both stops are located on the cylinder centerline, the optimal position to maximize travel adjustment and eliminate any detrimental side loading on the travel stops. Adjustable from 80˚ to 98˚.

Standard Options • • • • • • • •

Accessory Drive Slot Each actuator output shaft is provided with a precision machined accessory drive slot for low torque accessory devices such as limit switches and positioners. Various accessories can be directly mounted to the center body of models 135 through 1150 without the need for extra couplings or brackets. The result is a more compact and rigid assembly.
