1、 Electric three-way regulating valveProduct Overview
Electric three-way regulating valve
It has the advantages of high adjustment accuracy, stable and reliable action. Electric three-way merging regulating valve is mainly used to mix two fluids into a third fluid; Electric three-way diversion regulating valve is mainly used to divide one fluid into two fluids. The product can replace two single or double seat regulating valves that are mutually switchable, and is used for regulating and controlling media such as liquids, gases, and steam. The products produced by Wozhong Company are composed of PSL series and 3810 series linear electric actuators and three-way regulating valve bodies. (It can also be paired with other brands of direct travel actuators). The electric actuator is an electronic integrated structure with a servo amplifier inside. By inputting control signals (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled to adjust working parameters such as pressure, flow rate, liquid level, and temperature. It has the characteristics of sensitive action, simple connection, large flow rate, small volume, and high adjustment accuracy. The control accuracy and performance are significantly improved compared to the DKZ type.
