Our electric three-way regulating valves are composed of PSL series and 3810 series linear electric actuators and three-way regulating valve bodies. The electric actuator features an electronic integrated structure with a servo amplifier, and can control the valve opening with input control signals (4-20mADC or 1-5VDC) and power supply. This achieves regulation of process parameters such as pressure, flow rate, level, and temperature. The electric three-way regulating valve is characterized by its sensitive operation, simple wiring, high flow capacity, compact size, and high regulation accuracy. Its control precision and performance are significantly improved compared to the DKZ type. The electric three-way regulating valve offers high regulation accuracy and stable, reliable operation. The electric three-way mixing regulating valve is mainly used to mix two fluids into a third fluid; the electric three-way splitting regulating valve is mainly used to split a single fluid into two. Our three-way regulating valve products can replace two interlocked single and double seat regulating valves for the regulation and control of liquids, gases, steam, and other mediums.
