                  [Valve features]
                         Three electric valves, valve three through two seater, sleeve guide structure, regulatory agencies are divided into two kinds, the confluence of shunt flow, electric actuator for intelligent integration, without the servo amplifier, the input signal can be used in heat exchanger operation, two-phase adjustment and simple ratio adjustment.

                  [Adaptive condition]

                         The electric three - way regulating valve (three - way shunting / confluence) consists of direct stroke electronic actuator and three-way valve. Embedded servo function, standard signal receiving unified 4-20mA or 1-5V.DC, the current signal into linear displacement corresponding to the automatic control valve opening, continuous adjustment of the fluid in the pipeline pressure, flow, temperature, level and other parameters. The valve structure of the three-way valve adopts a cylinder thin-wall window and adopts the side direction of the valve core. Used to adjust the proportional control or bypass, adjust the fluid temperature control system is especially suitable for the oil industry in the heat exchanger, a three-way valve can replace two single seat valve or valve seat use, occupy small space, save the installation cost and pipeline.
