RH - extreme-duty
RH
RH extreme-duty hydraulic actuators are designed for demanding applications such as the adverse conditions found in mining and offshore industries. The robust double-acting hydraulic design with provision of four power cylinders results in a very compact footprint – in some cases even smaller than that of the valve.
Features
- Double-acting configuration with four hydraulic cylinders
- Dual rack design
- Designed for some of the most challenging valve actuation applications on earth
- Balanced, compact design
- Standard rotation 90° (+/-5°)
- Totally enclosed weatherproof housing
- Carbon steel construction
- Electroless nickel-plated cylinders with redundant piston seals
- Female input shaft allows direct mounting to valve topworks
- Mechanical interfaces to ISO 5211
- Lifting lugs to support the actuator and valve.
