SZDLQ electronic merging electric three-way regulating valve and SZDLX electronic electric three-way diversion regulating valve adopt cylindrical thin-walled window shaped valve core guidance. Equipped with 9610L series electronic linear electric actuator, capable of accepting 0-10 or 4-20mA DC signal drives valve opening and closing. The three-way merging regulating valve is used to mix two fluids, or the same fluid at different temperatures, into the same temperature fluid. A three-way splitter valve divides a fluid into two streams.
The nominal diameter of the electronic control valve ranges from 25mm to 300mm, and the nominal pressure of the electronic control valve is 1.6, 4.0, and 6.4MPa. The electronic control valve is suitable for fluid temperatures ranging from -60 ℃ to 450 ℃, and the control signal of the electronic control valve is 0-10 or 4-20mA DC. Different valve covers can be divided into two types: ordinary type and heat dissipation type.
