single seated electric water valve
ZAZP ZAZN type electric direct single&double seated modulating valve is the terminal control device of industrial process measurement and control system. It is composed of linear electric actuator and direct single, double plate modulating valve. It 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.
1. Usage
ZAZP/ZAZN type electric single, double plate modulating 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(Ⅲ 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 volum, etc. It is widely used in power generation, metallurgy, petroleum, chemical industry, light industry and boiler feed water.
