QUARTER TURN PNEUMATIC ACTUATORS SINGLE & DOUBLE ACTING SPS & SPD series DESCRIPTION The SPS & SPD series, heavy duty high performance design actuators, are for ProControl the long-standing products of the range. The reliability and firmness that distinguish them arise from a constant innovation research combined with the experience gained over the years.

KEY FEATURES • Fabricated entirely from carbon steel • Totally enclosed weatherproof housing • Scotch yoke mechanism to suit valve torque requirements • Relief vent to expel undesired overpressure • Low pressure pneumatic cylinder for supply pressures up to 12 bar design suitable for instrument air or sweet / inert gas applications or special application with material according to NACE requirements for sour gas supply medium • Carbon steel piston with dynamic floating O-ring seals coupled with lubricating piston guide rings • Carbon steel spring cartridge (only for single acting) with...

SPS & SPD series Quarter Turn ProControl actuator housings have been engineered considering latest industry standards as our starting point of improvement, the result is a more rugged, robust and strengthened product suitable for the most demanding applications such as modulating and offshore heavy duty services. Our actuators generate high torque outputs at a more cost effective price to our clients. ProControl actuators are made completely from fabricated carbon steel. COMPANY CERTIFICATIONS Every aspect of our company’s activities complies with SO 9001:2008 certified by Det Norske...

Scotch Yoke Mechanism SPS & SPD Series The scotch yoke mechanism is precisely positioned inside a perfectly sealed housing which protects it against corrosion in the most adverse environments. The housing also encompasses a stem thrust support device suitable to withstand the transversal forces generated during rotation and to ensure the proper alignment of the piston rod with the sliding blocks. Low rotational friction is also ensured by means of oversized precise fitted bronze yoke shaft bushings which contribute to extend heavy duty working life span. The scotch yoke mechanism transforms...

NOTE: - The scotch yoke housing is the same in canted & symmetric configuration - Seal material can change for high or low temperature application (NBR/VITON/FLUOROSILICONE) * WITH IMPACT TEST CERTIFICATE

Modular Design Construction ProControl scotch yoke actuators all share a common construction philosophy known as modularity, which is achieved by utilizing a consistent engineering design throughout our complete range. Our current range of scotch yoke actuators consists of various center body sizes. The center bodies have been designed to accommodate the widest variety of pneumatic and hydraulic power cylinders together with the widest variety of spring containers. The power cylinders can be assembled to either or both sides of the center body. The spring containers can be assembled onto...

Design Features MECHANICAL TRAVEL STOP Two adjustable mechanical travel stops to allow the fine adjustment of the valve angular stroke by means of stop screws, which are located one into the end flange of the spring container and the other into the end flange of the pneumatic cylinder, or on the mechanical manual hand wheel override, or on the end flange of the hydraulic manual override cylinder, depending on the actuator version. THE PNEUMATIC CILINDER The pneumatic cylinder is manufactured from carbon steel. The cylinder tube is machine polished and electroless nickel plated internally in...

PROCONTROL STANDARD KEYWAYS The assembly position of the actuator must be in accordance with plant requirements (which normally cylinder axis parallel to the pipeline or in some cases where spece is limited assembly may be perpendicular to the pipeline axis) and with the valve model. ProControl actuators have as a standard 2 90° keyways machined into the yoke which combined with our valve adaptation kit allows four 90° actuator positions. “1H” IS THE STANDARD MOUNTING FOR FAIL OPEN PROCONTROL ACTUATOR “9H” IS THE STANDARD MOUNTING FOR FAIL CLOSE AND DOUBLE ACTING PROCONTROL ACTUATOR Pro...

SPS Fast & Ultra Fast actuators ULTRA FAST SPS ProControl has engineered a special design which is fitted to all single acting spring return actuators consisting of an INTEGRAL QUICK EXHAUST VALVE DAMPER. This engineered product allows for fast and ultra-fast fail action stroking times. The product has been specifically designed for our pneumatic SPS series scotch yoke actuators. The principal of operation consists in discharging a large volume of stored air by spring stroke in the shortest possible time (Integral Quick Exhaust Valve), but at the same time it is essential to provide a...

Speed Curve Diagram MAIN CHARACTERISTIC • Operating time 0.1 to 2 sec. depending on the valve and actuator size and supply pressure • Available for all size of actuators • Operating pressure from 10 to 250 barg • Actuated valve: ball, butterfly, special Our Integral quick exhaust damper system allows a variety of features and benefits such as : • Use of actuated valves with fast and ultra-fast fail safe stroking times • Special damping system in order to avoid serious damage to the valve drive train and actuator • Combined On-Off and Modulating service (2 applications with one single...
