K-West Inc. | RCS Electric Actuators

In its fifth decade of production, RCS® maintains a peerless reputation for performance, reliability, and versatility for the manufacture of quarter-turn and Spring Return electric actuators. Proudly made in America since 1968, RCS actuators are designed to automate flow control devices for a wide and varied range of applications, from ball, butterfly, and plug valve automation to more specialized applications such as multi-turn and rotary choke valves. A comprehensive range of modular control accessories allow RCS® electric actuators to be tailored to address the most complex process control requirements for either on-off, modulating or digital network protocols, and the extensive network of factory-trained authorized service centers provides after market support for technical and application questions.
