Rotork
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
• 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
