Working principle of zdlp- 16 electronic control valve

ZDLP electronic-electric single-seat control valve consists of PS series and 36 10 series straight-stroke electric actuators and low flow resistance straight-through single-seat valves. (It can also be equipped with other brands of straight stroke actuators). Electric actuator is an electronic integrated structure with servo amplifier. By inputting control signal (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled, and the working parameters such as pressure, flow, liquid level and temperature can be adjusted. It has the characteristics of sensitive action, simple connection, large flow, small volume and high adjustment accuracy. Compared with DKZ, the control accuracy and performance are obviously improved.

Principle: The motor power supply is 220VAC or 380VAC, and the control signal is 4~20mA. There is a controller in the valve. The controller converts the current signal into the angular stroke signal of the stepping motor. When the motor rotates, the gear, lever or gear plus lever drives the valve stem to run, realizing the feedback of linear stroke or angular stroke: when the motor is running, the sliding rheostat with three joints outputs the positioning signal of the valve, and there are also three limit signals (full open).
