ZAZP ZAZN type electric direct single/double plate modulating valve( single /double seated adjusting valve) is the terminal control device of industrial process measurement and control system. It is composed of linear electric actuator and direct single 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.
ZAZM electric sleeve modulating valve has many advantages. Its rated flow coefficient is big. Valve spool axial direction unbalanced force is small. The operation area is stable and usage differential pressure is large. It is widely used in various fields.
The regulated flow characteristic of ZAZM electric socket modulating valve has regulated equal percent flow characteristic and line flow characteristic.
We can offer:
Three series of linear actuator for the valve:
1.Bernaed linear actuator: intelligent , precise and expensive.
2. SD series -Introduced Bernard technology linear actuator: intelligent, precise, Bernard technology, made in China ,cheap.
3. DKZ linear actuator: made in china, precise and cheaper.
Usage
ZAZ 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 volume, etc. It is widely used in power generation, metallurgy, petroleum, chemical industry, light industry and boiler feed water.
