RH (hydraulic) actuators-Image

Rack and pinion actuators often offer the most economical solution for quarter-turn valves that have a fairly constant torque requirement throughout the stroke.

RH (hydraulic) actuators are available in five body sizes to produce torque output up to 3,400 Nm (30,000 lbf-in) at operating pressures up to 250 bar (3,600 psi). They are available in either double-acting or spring-return configurations.

  • Heavy-duty cast iron bodies.
  • Electroless nickel-plated cylinders for corrosion resistance.
  • Nickel-plated, anti-blowout pinion.
  • Valve mounting dimensions per ISO 5211 DIN 3337.

See RH literature page for further details.
