ZDLQ/ZDLX electronic electric three-way diversion valve
ZDLQ electronic three-way merging control valve and ZDLX electronic three-way diversion control valve are composed of PS series and 3610 series linear electric actuators and low flow resistance straight through single seat valves. (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.
The electronic electric three-way regulating valve has the advantages of high regulation accuracy, stable and reliable action. Confluence type is mainly used to mix two fluids into a third fluid; Split flow type is mainly used to divide one fluid into two fluids. This 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.

Control valveAlso known as control valve, in the field of industrial automation process control, it is the final control component that changes process parameters such as medium flow rate, pressure, temperature, liquid level, etc. by receiving control signals from the regulating control unit and using power operation. It is generally composed of an actuator and a valve. If according to the characteristics of the stroke, the regulating valve can be divided into straight stroke and angular stroke; According to the power used by the actuator, it can be divided into three types: pneumatic control valve, electric control valve, and hydraulic control valve; According to its function and characteristics, it can be divided into three types: linear characteristics, equal percentage characteristics, and parabolic characteristics. Regulating valves are suitable for media such as air, water, steam, various corrosive media, mud, oil, etc.
