The ZMAQ/ZMAX pneumatic thin film three-way regulating valve has two modes of action: merging and splitting. The valve core structure adopts a cylindrical thin-walled window and a three-way valve guided by the side of the valve core, which can replace two two-way valves and one three-way connecting pipe in some situations and is widely used. It is commonly used for two-phase regulation of heat exchangers and can also be used for simple ratio regulation.

characteristic

The pneumatic thin film three-way regulating valve adopts a cylindrical thin-walled window shaped valve core guidance, which is different from the liner guidance of the plunger shaped valve core. Equipped with a multi spring actuator, it has the advantages of simple structure, light weight, small volume, and convenient disassembly and assembly.
