The pneumatic control ball valve is a flagship product of WUXI XINMING AUTO-CONTROL VALVES INDUSTRY CO., LTD., integrating a high-precision ball valve with an intelligent pneumatic actuator. It achieves precise adjustment from 0-90° with a 4-20 mA or 0.5-6 bar signal, with a repeatability error ≤ ±0.5%, providing reliable and rapid shut-off and regulation functions for process automation. The key phrase "pneumatic control ball valve" is integrated throughout the design, ensuring rapid, safe, and zero-leakage operation with every opening and closing.
Our Advantages:
Modular Design
Different actuators can be selected for the same valve body, reducing delivery time by 30%.
Low Operating Costs
Air-driven, energy consumption is only 1/3 of electric; automatic reset in case of air source failure.
High Sealing Life
After 500,000 cycle tests, the leakage rate is still better than Class VI.
Fireproof and Anti-static
Complies with API 607/ISO 10497, ensuring safety in flammable and explosive environments.
Immediate Response
Opening and closing ≤1 second, adjustment linearity >95%, significantly improving system control accuracy.
