Description

The self-operated pressure regulating valve does not require external energy, and uses the controlled medium itself as the power source tointroduce the actuator to control the spool position to change the flow area, so as to achieve the purpose of changing the flow rate and stabilizethe pressure before (or after the valve). it has the advantages of sensitive action, good sealing, small pressure fluctuation, etc.lt is widely usedn various industrial eauioment for the automatic contro of gas, iouid, and steam medlum oresure relief and pressure relef Selfoperatedpressure regulating valves are divided into two types: rear valve and front valve.
