The three-way valve can be divided into three-way shunt valve, three-way confluence valve or switch control according to the requirements of process conditions.

Generally, it can be widely used instead of two single seat regulating valves or two through valves and a three-way connecting pipe.

It is mainly used for ratio regulation and switch control of liquid, gas, steam and other media, such as temperature control and two-phase ratio regulation of heat exchange device.

1. Balance the piston structure and double guide structure to make the valve core move up and down smoothly and reduce the vibration of the valve core.

2. The piston type pressure balance structure reduces the unbalanced force, so that the valve can work safely, sensitively and accurately in the situation of high temperature and high pressure difference

3. The upper and lower valve cores adopt an integrated structure, and the curve of the upper and lower valve cores can adopt a linear and an equal percentage, which makes the adjustment range of the valve wider
