The electric three-way regulating valve is usually used in the heat exchanger to adjust the temperature of the fluid. It has the characteristics of high adjustment precision and good adjustment performance. The stock inlet fluid is divided into two export fluid, or the two inlet fluid into the stock outlet fluid. Nominal diameter and pressure difference is small, the confluence valve can be used in the shunt, but the nominal diameter is larger than 80mm and the pressure difference is larger, or the use of the shunt valve is appropriate. This product conforms to GB/T4213-92.
