Self-contained Hydraulics

The Rotork Self-contained Hydraulics provide high-integrity fail-safe valve operation without the need for any external power supply. The self-contained system is suitable for workshop or field mounting on a wide range of rotary and linear operated valves and dampers. It offers a cost-effective solution for actuator applications where operation is infrequent. Typical applications include emergency shutdown valves and over- or under-pressure protection at remote, unpowered locations.

  • Completely self-contained spring-return failsafe actuators
  • Cost-effective solution for infrequently operated valves and dampers
  • Adaptable for quarter-turn or linear service
  • Simplified control circuit with a minimum of components
  • Built-in temperature compensation
  • High-pressure zero-leakage control system
  • Watertight or explosionproof construction
  • Fail open or closed
  • High-integrity stainless-steel tube and fittings
  • Manual reset after operation
  • 10 bar (150 psi) or 100 bar (1,500 psi) operating pressure suitable for actuator displacements up to 13.2 L (3.5 US gal)
