Part of our portfolio of SSS surface safety system actuators is the Model RV reduced-volume hydraulic actuator, which reduces the overall cost of the operating system. This actuator operates valves ranging from 2 to 4 in and valve working pressures to 5,000 psi [345 bar]. It also utilizes a translating cylinder design, which makes maintenance of the single T-seal inherently simple. The inspection window provides visual indication of the gate valve position and allows a side-mount magnetic limit switch to be installed.

The Model RV actuator’s design incorporates our patented Quick-Disconnect bonnet, permitting installation or removal of the actuator without depressurizing the gate valve. Additional model options include the RV with a one-piece stem and mechanical opener, and the RV with a heat-sensitive lock-open device.

Features

  • Compact design that allows installation and service in confined areas 
  • Quick-Disconnect feature permits removal of actuator without depressurizing the valve, which greatly reduces downtime and lost production 
  • Inspection window provides visual indication of valve position 
  • External safety relief device protects the actuator from overpressurization
