hydraulic valve actuator / rotary / double-acting / rack-and-pinion
Max.: 5,650,000 Nm (4,167,226 ft.lb)
Min.: 0 Nm (0 ft.lb)
RHQ actuators are designed for some of the most challenging valve actuation applications on earth. They are an excellent choice for the demanding requirements and adverse conditions found in applications for mining and offshore. The balanced design has a very compact footprint for a given output. Integral lifting lugs are designed to support the weight of both the actuator and the valve.
Output torque up to 5,650,000 Nm (50,000,000 lbf.in).
Hydraulic, double-acting actuators
Ductile cast-iron or carbon-steel totally enclosed weatherproof housings (IP68)
Lower swept volume than vane type actuators
Electroless nickel-plated cylinders with redundant piston seals
Precision machined rack and pinion mechanism
Female input shaft allows direct mounting to valve topworks
Standard rotation 90° (+/- 5°)
Supply pressures to 207 bar (3,000 psi)
