ZHA/BQ (X) light and small pneumatic thin film three-way flow regulating valve (referred to as three-way valve) is an execution unit in industrial process control. It can replace two regulating valves used at the same time and play the role of diversion or merging. This product uses a cylindrical thin-walled window shaped valve core as a guide and is equipped with a multi spring actuator. It has the characteristics of simple structure, light weight, stable and reliable adjustment, and small space occupation. It is widely used for temperature control of heat exchangers and can also be used for automation process control in industries such as petroleum, chemical, power plant, metallurgy, etc.

Key Features:
1. The direction of fluid action on the valve core is in the open state, so the valve can work stably.
2. In addition to the guiding effect of the liner in the upper valve cover, the side of the valve core and the inner surface of the valve seat also have guiding effects, so the guiding area is large and the work is reliable.
3. Equipped with a pneumatic thin film multi spring actuator, it has a small volume and light weight.
