CP
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.

LP/LH
Rotork linear actuators offer the advantages of compact size, high performance and a simple but highly reliable design. They are ideal for operating on/off and control functions of both globe and wedge gate valves. Both spring-return and double-acting configurations are available with either pneumatic or hydraulic cylinders.

GP/GH
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.

CQ
The CQ range provides an innovative fully-concentric and balanced actuator design for quarter-turn valves. The design features a helical mechanism that transforms linear piston motion into quarter-turn valve stem rotation. CQ actuators provide a much higher torque output for a given footprint than scotch yoke designs typically utilised to operate many quarter-turn valve types. It is therefore ideally suited for installation in confined spaces. Further, Rotork’s unique helical pin design provides higher efficiency than a helical gear mechanism utilised by other valve actuator manufacturers.As standard, the CQ torque output profile, like that of a scotch yoke actuator, is engineered to parallel the torque demand profile typically found with popular quarter-turn valve types. The CQ design however is unique in that the torque profile can be custom engineered and manufactured to meet specific, non-standard valve torque requirements.In our experience, the CQ standard range of sizes is suitable for applications that require a pneumatically powered actuator with torque demand less than 150,000 Nm. However, we also engineer CQ actuators with greater output and/or hydraulic power. Please apply to Rotork for these applications.

HPU
Hydraulic power units (HPU’s) complement our extensive offering of rotary and linear actuators. We have over three decades of experience in their manufacture with units in service in a variety of plants and pipelines in locations spanning the globe. Although our HPU’s are primarily intended to power our hydraulic actuators they are of course suitable for other applications as well. And, in order to provide a complete range of options to best meet the requirements of any application, RFS also has the Skilmatic range of self-contained electro-hydraulic actuators.

Control Networks
Modern facilities require up to date communications right down to plant level. Plant managers demand more information quicker than ever before. Process operators need full control facilities at all times of the day and night. Maintenance managers want information so that their services can be scheduled economically. To meet these requirements, design engineers include field communications networks to allow every piece of critical plant to be controlled and monitored by computer. These computers are assigned to management operations and maintenance tasks within their own network, exchanging data about the equipment and processes under their control.
