SY Series Scotch Yoke
Actuators
Engineering Creative Solutions for Fluid Systems Since 1901
MODULAR DESIGNThe Pratt Industrial SY series scotch yoke actuator has a highly efficient and interchangeable modular design (air cylinder, power drive, spring pack, and override module) providing for easy field modification and serviceability.
NAMUR MOUNTINGNAMUR VDI/VDE 3845 dimensional standard on all sizes. No special blocks or hardware required to mount solenoid valves, limit switches, or positioners.
DEGREE OF TRAVELEach SY actuator has been engineered with bidirectional travel stops which allow for total travel adjustment between 80° and 100°.
ISO MOUNTINGDesigned in accordance to the ISO 5211 dimensional and torque range specification for easy and cost effective automated valve assemblies.
All critical-to-operation bearings have been designed with self-lubrication allowing for maximum energy transfer directly to the valve stem. The pre-compressed spring pack minimizes radial loads on the piston rod and increases the service life and durability of the actuator. Replaceable bearings protect all sliding and rotating components for maximum life.
SELF-LUBRICATINGAll SY series actuators have been designed to be completely self-lubricating, requiring no further lubrication, ensuring maximum wear resistance and long cycle life.
QUALITY ASSURANCE100% of all units are factory pressure tested, no-leak verified, and torque performance guaranteed prior to shipment.
WATERTIGHT DESIGNO-rings are sized to exact specifications creating a watertight design.
SAFETY LOCKEach SY series actuator has been engineered with safety as its highest priority. The SY series actuator features a specially designed safety lock mechanism so that the spring module can only be removed from the power module when the spring is fully decompressed. This important safety feature prevents accidental release of spring tension. The spring lock mechanism safely retains the spring module under load, and prevents the module from being removed when the actuator is under load conditions.
INTEGRAL CHECK VALVEAn integral check valve is incorporated into the design of the SY series actuator to prevent over pressurizing and foreign material from getting inside the unit. This prevents premature break down and increases the life of the actuator.
POWER YOKE DESIGNEach scotch yoke power mechanism has been precisely machined to exact tolerances and fitted with high quality, self-lubricating bearings, piston rod, and guide block for high efficiency energy transmission, smooth operation, and trouble-free service.
HYDRAULIC OVERRIDEThe SY series offers a hydraulic override cylinder module on all spring return models. This important feature does not increase the overall length of the body.
CORROSION RESISTANCEEach unit comes standard with a minimum of three progressive stages of internal and external coating for corrosion resistance. The inner lining of the cylinder wall is coated with infused PTFE, thereby enhancing internal corrosion resistance and self-lubrication.
HANDLINGThe SY series actuators come with easy to handle eye bolts which make for ease of lifting and transporting.

MECHANICAL OPERATION AND SIZING CONSIDERATIONS
The Scotch Yoke is a mechanism designed for converting linear force into rotation torque, usually at higher torque outputs than other conventional mechanical devices. The piston and spring mechanisms are directly coupled to a sliding yoke and pin device that provides for the transmission of power in a highly reliable and smooth operation. This type of mechanical device provides for the highest torque outputs to be generated at the beginning and
ending of the stroke cycle, and at decreasing speeds during the most critical point in the cycle; unseating and seating valves at their opening and closing phases. This design allows for the most desirable and efficient use of energy in large valve applications.
When sizing scotch yoke actuators, it is important to take into consideration the following:••••••
Type of application desired (double acting or spring return service) Proper determination of the ‘sizing torque'Understanding of the valve type and operation (ball, butterfly, plug, etc.)Knowledge of the related process media (oil, water, gas, powders, etc.)Review of minimum and maximum operational temperatures and pressures of the line media Consideration of environmental conditions which may affect the installationFinally, a safety and regulation review to ensure all aspects of the operation are compliant•
