I. Overview of ZJHF pneumatic three-way control valve

     有合流和分流两种结构形式。 ZJHF pneumatic three-way control valve has two types of structure: merge and divert. The spool structure adopts a cylindrical thin-walled window and the spool is guided sideways. In some cases, the three-way valve can replace two two-way valves and one three-way nozzle and wait until it is widely used. It is often used for two-phase adjustment of heat exchanger , Can also be used for simple ratio adjustment. When the nominal diameter and pressure difference are small, the combined valve can be used for diverting occasions and can be used interchangeably, but the diverting occasions with nominal diameter greater than 80mm and larger pressure difference cannot be used interchangeably.
