ZJHQ pneumatic three-way control valve is composed of multi-spring pneumatic diaphragm actuator and three-way shunt (confluence) valve body. Pneumatic membrane actuators have the advantages of low height, light weight, large flow capacity, and easy installation and maintenance. Pneumatic three-way control valve is equipped with electric valve positioning or pneumatic valve positioner, which can realize automatic adjustment and control of fluid medium in process pipelines, and is widely used in precise control of process parameters such as pressure, flow, temperature of gas, liquid, steam and other media. , liquid level and other parameters are kept at the given value.

The spool structure of the pneumatic membrane three-way control valve adopts a cylindrical thin-walled window and is guided by the side of the spool. The valve body is a three-way structure, that is, one in and two outs (pneumatic three-way diverting control valve), two in and one out (pneumatic three-way diverting control valve), so as to achieve fluid mixing heating or cooling, or fluid unequal diversion, satisfying Different industrial and mining requirements.

ZJHQ pneumatic three-way control valve body has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics and convenient maintenance. Pneumatic three-way control valve is used for proportional adjustment or bypass adjustment, especially for the adjustment of fluid temperature control system of heat exchanger in petroleum industry. One three-way valve can be used instead of two single-seat valves or double-seat valves, occupying space. Small size, saving installation pipeline and cost.
