FeatureS
• Totally enclosed, weatherproof housing in
high strength nodular cast iron, suitable for
use in hostile environments.
• Integral vent valve prevents accidental
pressurisation.
• Compact rack and pinion design provides
simple construction.
• RPHD double cylinder design allows different
torques in opening and closing.
• Precise angular stroke adjustment between
80° and 100°.
• Electroless nickel plated and polished
cylinder for corrosion resistance and minimal
friction.
• Low hysteresis and high sensitivity piston
seals prevent sticking problems.
• Bushings in sintered bronze charged with
PTFE for minimal friction and long life.
• Fully encapsulated RPHS spring module
ensures personnel safety and simplifies
assembly.
• Cast steel option available.
General application
RPHD and RPHS are hydraulic high-pressure
actuators suitable for any low-torque quarter
turn application such as ball, plug, butterfly
valves or dampers.
