ZDLQ electronic electric three-way combination regulating valve and ZDLX electronic electric three-way shunt regulating valve are composed of PS series and 3610 series direct travel electric actuator and low flow resistance through single-seat valve. (can also be matched with other brands of direct travel actuator). The electric actuator is an electronic integrated structure, with servo amplifier, input control signal (4-20mADC or 1-5VDC) and power supply to control the valve opening, to achieve the adjustment of pressure, flow, liquid level, temperature and other working parameters. It has the characteristics of sensitive action, simple connection, large flow, small size and high adjustment accuracy.
The control accuracy and performance are significantly improved than DKZ type.
The electronic electric three-way regulating valve has the advantages of high adjustment precision, stable and reliable action. Confluence type is mainly used to mix two kinds of fluid into a third kind of fluid; The split-flow type is mainly used to split one stream of fluid into two streams. The product can replace two mutual switch single, double seat regulating valve, used for liquid, gas, steam and other media regulation and control.
