RH - heavy-duty
RH
RH heavy-duty actuators are a compact, economical and robust solution for quarter-turn valves that have a fairly constant torque requirement throughout the stroke and are designed to operate ball, butterfly, plug and other quarter-turn valves for either on/off or modulating service.
