The pneumatic threaded three-way ball valve is a control valve that uses compressed air as a power source and employs a threaded connection. It achieves fluid flow switching or shut-off through the rotation of a ball. Its core features combine the high-efficiency driving characteristics of a pneumatic actuator, the convenient installation advantages of a threaded connection, and the multi-channel control capabilities of a three-way structure.
It can achieve rapid and stable control of various media such as liquids, gases, and steam in multiple industrial fields, including chemical, petroleum, water treatment, and food processing, and is particularly suitable for scenarios requiring automated pipeline switching.
Compared to manual three-way ball valves, this product replaces manual operation with a pneumatic actuator, significantly improving switching speed and control accuracy. It can also be used with accessories such as solenoid valves and positioners to achieve remote automated control, reducing manual maintenance costs.
Compared to flanged pneumatic three-way ball valves, its threaded connection design is more suitable for small-to-medium diameter pipelines (typically DN15-DN100), requiring no additional flange fittings during installation, facilitating disassembly, and effectively saving pipeline space.

Features of Pneumatic Threaded Three-Way Ball Valve:
- Fast Response: Pneumatically driven, short response time (typically <1 second), suitable for high-frequency switching scenarios.
- High Reliability: Spark-free design, suitable for flammable and explosive environments (such as chemical and petroleum industries).
- Corrosion Resistance: Valve body materials include stainless steel (304/316), nickel-plated carbon steel, etc., suitable for corrosive media.
- Low Leakage: Metal seal rating up to ANSI Class VI, soft seal achieves zero leakage.
- Easy Maintenance: Modular design, actuator and valve body can be quickly disassembled, reducing downtime.
Applications of Pneumatic Threaded Three-Way Ball Valve:
- Chemical Industry: Controlling the flow direction of corrosive media such as acids, alkalis, and solvents.
- Water Treatment: Regulating water flow direction to achieve backwashing, bypass filtration, and other functions.
- Food and Pharmaceutical: Sanitary design (e.g., 316L material) meets aseptic production requirements.
- Oil and Gas Transportation: Used for pipeline branching or merging to optimize fluid distribution. HVAC system: Regulates the splitting or combining of hot and cold water in air conditioning systems to balance the system load.
