The pneumatic film three-way regulating valve is guided by a cylindrical thin-walled window-shaped spool, which is different from the bushing guiding of the plunger-shaped spool. Equipped with a multi-spring actuator. The utility model has the advantages of simple structure, light weight and small volume. Easy to disassemble and so on. It is widely used to precisely control media such as gas and liquid. Process parameters such as pressure, flow temperature and liquid level are kept at a given value. It is suitable for the case where one fluid is divided into two through a three-way valve or two liquids are combined into one fluid through a three-way valve.
