The ZHA/BS series lightweight pneumatic thin film sleeve regulating valve is a new generation product independently developed by our factory. It has the advantages of small size, lightweight, simple structure, high flow coefficient, large allowable pressure difference, good stability, strong adaptability, and easy assembly, disassembly, and maintenance, and is therefore widely used.

ZHA/BS series light and small pneumatic thin film sleeve regulating valve structural characteristics:

1. A sleeve valve is a cylindrical sleeve inserted into a single seat valve body, guided by the sleeve, and equipped with a valve plug (spool) that can move freely in the axial direction. A hole or window on a sleeve with certain flow characteristics.
2. The sleeve is fastened to the valve body with a sealing gasket, and threads are not used when installing the sleeve.
3. There is a balance hole on the valve plug (valve core), which can effectively eliminate most of the axial unbalance acting on the valve plug.
4. The actuator is multi spring, small in size, light in weight, and the connection between the push rod and the valve stem uses slotted nuts for easy assembly, disassembly, and maintenance.
