Overview
S-Series subsea valve actuators use modified HY and HYL-Series valve actuators to provide subsea valve automation of rotary and linear valves and are available in spring-return and double-acting configurations. The design incorporates the option for industry standard ROV override interfaces and control systems for remote signalling and operation.
Applications
Automation of subsea rotary and linear valves.
Operating Ranges
- Supply Pressure: 13 to 250 Barg (90 to 3,625 psig)
- Torque Output: 200 to 500,000 Nm (1,770 to 4,425,000 lbs.in.)
- Thrust Output: Up to 222,000N (50,000 lbs)
Key Features & Benefits
- Operation in water depths of 2,000m using pressure compensated designs, 200m for non pressure compensated designs
- Electroless nickel plated cylinder as standard with hard chromium plating, Xylan® or Electro-film available
- Springs contained within a fully welded canister (which is post weld heat treated) to guarantee simple and safe removal
- Springs are scragged (set removal) in order to warrant optimum and stable performance
- Easy and economical maintenance due to simplified design, no special tools required for installation and maintenance
- Compliant to PED 97/23/EC
- Several yoke lever configurations (cants) allowing selection of the actuator output torque that best suits the valve torque characteristic.
- Suitable for high frequency and high speed operation
- Guide bar frame design used to eliminate side forces and low friction seals ensure high efficiency
