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 actuators are available in five body sizes to produce torque output up to 3,400 Nm at operating pressures up to 250 bar. They are available in either double-acting or spring-return configurations.
