Overview of pneumatic three-way regulating valve

The pneumatic three-way regulating valve is composed of a multi spring pneumatic diaphragm actuator and a three-way confluence (diversion) valve with a cylindrical thin-wall window valve core. It has simple structure, light weight, sensitive action and accurate flow characteristics. Equipped with electric pneumatic valve positioning or pneumatic valve positioner, it can realize the automatic regulation and control of the fluid medium in the process pipeline. Pneumatic three-way regulating valve is widely used to accurately control the process parameters of gas, liquid, steam and other media, such as pressure, flow, temperature, liquid level and other parameters to maintain at the given value. It is suitable for dividing a fluid into two flows through the three-way valve or combining two fluids into one fluid through the three-way valve.

Zjhf and zjhh pneumatic three-way regulating valves adopt cylindrical thin-wall window valve core guidance, which is different from the bushing guidance of plunger valve core. Equipped with multi spring actuator, it has the advantages of simple structure, light weight, small volume, convenient disassembly and assembly, etc. It is widely used to accurately control the process participation of gas, liquid and other media, such as pressure, flow, temperature, liquid level to maintain at the given value. It is suitable for dividing a fluid into two flows through the three-way valve or combining two fluids into one fluid through the three-way valve.

There are two kinds of pneumatic three-way regulating valves: three-way confluence and three-way diversion. Nominal pressures are PN16, 40, 64; Nominal diameter range dn25-300. The applicable fluid temperature ranges from -60 ℃ to +450 ℃. The leakage standard is level IV. There are two kinds of flow characteristics: straight line and parabola.
