Pneumatic control valves are the core components of industrial automation fluid control systems. Using compressed air as the power source, they drive actuators through positioners to precisely adjust valve opening, thereby regulating medium flow, pressure, temperature, and other process parameters.
Wuxi Quankong Valve offers a comprehensive range of pneumatic control valves including single-seated, double-seated, cage-guided, and three-way types, covering sizes from DN15 to DN400 with pressure ratings from PN16 to PN640.
Key Features
- Fast Response: Pneumatic actuators offer millisecond-level response for demanding closed-loop control
- High Precision: Intelligent positioners support 4-20mA/HART/fieldbus, with positioning accuracy up to ±0.5%
- Wide Application: Suitable for steam, water, oil, gas, chemicals, and various industrial media
- Intrinsically Safe: No electrical spark risk — ideal for hazardous areas (Ex ia IIC)
- Fail-Safe Options: Available in spring-return (FO/FC) configurations for emergency shutdown
