Product details

First, an electronic three-way control valve overview

Electronic three-way electric control valve with high precision, stable and reliable operation and so on. The confluence type is mainly used to mix two fluids into a third fluid; the split type is mainly used to divide one fluid into two fluids. This product can replace the two single-and double-seat switch valves, which are used for the regulation and control of liquids, gases, steam and other media.

Second, the electronic three-way valve main technical parameters and performance indicators

By the PS series and 3610 series of straight-stroke electric actuator and low flow resistance through the single seat valve. (Also can be equipped with other brands of straight-line Cheng executive body). Electric actuator for the electronic integration structure, with a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve opening, to pressure, flow, level, temperature and other parameters adjust. With sensitive action, simple connection, large flow, small size, high regulation accuracy. Control accuracy and performance than the DKZ type has significantly improved.
