Remote Pressure Control Regulating Water Valve
MOQ: 1
Introduction
ZAZP type electric direct double plate regulating valve( double seated adjusting valve) is the terminal control device of industrial process measurement and control system.Remote regulating valve is composed of linear electric actuator and direct double plate modulating valve.Remote regulating valve can change the position of closure member in the valve- valve spool automatically according to system control signal, and change the circulation area of valve spool and valve plate, that is to change the resistance coefficient of valve in order to regulate the technological parameter as medium volum, pressure and liquid level.
Usage
ZAZ type electric single, double plate Remote regulating valve is the combination product of modulating valve body and linear electric actuator. Its power is 220V, 50HZ. It receives uniform standard signal 4~20 mA( type) or 0~10 mA(II type) and controls the opening degree of valve according to the signal so as to regulate technological parameters such as temperature, pressure and liquid volume, etc. It is widely used in power generation, metallurgy, petroleum, chemical industry, light industry and boiler feed water.
