RR 931 throttle control valve allows adequate reduction and regulation of flow rate of natural gases and LPG. RR 931 operation is based on gas throttling by reducing the valve passageway. The throttle control valves are intended to be used in industrial equipment, in natural gas transportation and distribution systems. RR throttle control valve can be equipped with manual/ pneumatic or electric actuator. Various accessories can also be provided: position indicators, remote controls, etc.
