Overview

The ZJZP type pneumatic diversion control valve of Tingyang Company's pneumatic double seat control valve is composed of a multi spring pneumatic diaphragm actuator and a three-way diversion (merging) control valve body. Pneumatic thin film actuators have the advantages of low height, light weight, high flow capacity, and easy installation and maintenance. Pneumatic three-way control valve, equipped with electrical valve positioning or pneumatic valve locator, can achieve automatic adjustment and control of process pipeline fluid medium. It is widely used for precise control of process parameters such as pressure, flow rate, temperature, liquid level, etc. of gas, liquid, steam and other media to maintain them at given values.

Product Details

Ting Yang Company'sPneumatic double seat regulating valve, pneumatic three-way regulating valve, ZJZP type pneumatic diversion regulating valve，The pneumatic three-way regulating valve is composed of a multi spring pneumatic diaphragm actuator and a three-way diversion (merging) regulating valve body. Pneumatic thin film actuators have the advantages of low height, light weight, high flow capacity, and easy installation and maintenance. Pneumatic three-way control valve, equipped with electrical valve positioning or pneumatic valve locator, can achieve automatic adjustment and control of process pipeline fluid medium. It is widely used for precise control of process parameters such as pressure, flow rate, temperature, liquid level, etc. of gas, liquid, steam and other media to maintain them at given values. The valve core structure of the pneumatic thin film three-way regulating valve adopts a cylindrical thin-walled window and is guided by the side of the valve core. The valve body is a three-way structure, with one inlet and two outlets (pneumatic three-way diversion control valve) and two inlets and one outlet (pneumatic three-way diversion control valve), to achieve fluid mixing heating or cooling, or uneven fluid diversion, meeting the requirements of different industrial and mining uses. The valve body of the pneumatic diaphragm three-way regulating valve has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, precise flow characteristics, and easy maintenance.
