Rotork Fluid Power Actuators

CP range pneumatic actuators are a versatile, modular, scotch yoke design available in both double-acting and spring-return configurations. The compact and efficient design yields high torques even at low pressures. The design concepts found in Rotork's large, heavy-duty actuators has been applied to the CP range, which brings heavy-duty actuator qualities to small, quarter-turn actuators. The actuator body is of rugged, ductile cast iron available in four body sizes. Cylinders are manufactured from carbon steel, electroless nickel-plated. Pneumatic actuators in double-acting and spring-return configurations Corrosion resistant cylinders Actuators certified to IP 66M/67M Actuators certified to ATEX 94/9/EC Actuators certified in accordance with PED 93/27/EC Torque output to 4,500 Nm (39,800 lbf-in)

The DH range of quarter-turn hydraulic vane dampers are engineered to provide a simple, reliable solution to inherent problems often seen in swing check valve applications: namely down line surges from rapid disc reseating and excessive valve wear due to the disc flutter produced at some flow rates. The rugged design features a self-contained hydraulic system that incorporates an easily adjusted valve for simple yet precise throttling controlin both directions. This closed loop hydraulic circuit protects the valve from potential valve contamination.

The GO range of pipeline actuators are designed to use pipeline gas as the motive power source. They utilise our robust GH and RH quarter-turn prime movers and are field proven in installations around the world. Control configurations are available to meet virtually any operational requirements. Scotch yoke and rack & pinion double-acting actuators Low- or high-pressure control logic options ASME certified tanks Hydraulic manual override standard Speed control in both directions standard PED or ASME approved gas/oil and power gas storage tanks Actuators certified to IP 66M/67M Actuators certified to ATEX 94/9/EC Actuators certified in accordance with PED 93/27/EC Torque output to 600,000 Nm (5,000,000 lbf-in)

GP (pneumatic) and GH (hydraulic) range scotch yoke actuators are designed to provide a rotary, quarter-turn movement for either on/off or modulating duty. The rugged yet compact design is available with two different yoke designs. The classic symmetric yoke delivers peak torque at both ends of stroke. Alternatively, they can be supplied with canted torque arms designed to deliver peak torque at only one end of stroke. Use of canted arms can often reduce actuator size, weight and cost for valves with appropriate torque demand characteristics.

The HPG range of pipeline actuators are designed to use pipeline gas as the motive power source. They utilise our robust scotch yoke mechanism field proven the world over in all types of fluid power applications. Manual override is a standard feature of the range. Our design incorporates a separate cylinder for hydraulic override to ensure complete separation of high-pressure pipeline gas from the hydraulic fluid. The use of an independent override cylinder allows replacement of power cylinder seals without removal of the actuator from the valve and will even allow for manual operation while the power cylinder is disassembled. Control configurations are available to meet virtually any operation requirements.

K-TORK vane actuators are available in both double-acting and spring-return configurations with torque outputs up to 18,300 Nm (155,000 in-lbs). K-TORK is a true rotary actuator - there is no sideload transferred to the actuator housing or valve stem. Additionally, K-TORK actuators provide a simple, proven method to mount fail-safe springs, manual overrides and control accessories. The vane actuator design provides high torque output in a compact size. The dual-opposed lip seals eliminate all pressure-retaining o-rings in the actuator, providing the user with a long, trouble-free operating life.
