Feature
Parameter

RVZZYP single-seat self-operated pressure control valve (Pressure control valve for short) is an actuator product that realizes automatic regulation by use of energy of regulated medium, without any additional energy. The product can work in the place without electricity and gas and energy can be saved. Pressure setting value can be adjusted an option in operation. Flow open flow characteristic is applied. The product is quick-acting, with good sealing performance, so it is widely applied to automatic control of pressure reduction and stabilization (used for after-valve regulation), or pressure relief and stabilization (used for before-valve regulation) of gas, liquid and steam medium in industrial equipment of petroleum, chemical engineering, electric power, metallurgy, foodstuff, light textile, machine manufacturing and residential architectural complex.etc
