Control Valves
Pneumatic Control Valve
- Simple Control: Uses compressed air as power source with simple and clear control system
- Fast Response: Responds quickly to control signals for timely regulation
- Intrinsic Safety: Uses pneumatic actuators without requiring additional explosion-proof measures
- Compact Structure: Equipped with multi-spring actuators, featuring compact structure, light weight, and responsive operation
- Long Service Life: Long-term operation without requiring repair, providing high-efficiency process control
- Optimized Flow Path: S-shaped streamline flow path minimizes pressure drop loss, with large valve capacity and good flow characteristics
Pneumatic Control Valve uses compressed air as the power source and a cylinder as the actuator, and drives the valve through accessories such as electric valve positioners, converters, solenoid valves, and holding valves to achieve on-off or proportional control. Pneumatic control valves are used to regulate the flow, pressure, and liquid level of the medium. According to the signal from the regulating section, the valve opening is automatically controlled to achieve regulation of medium flow, pressure, and liquid level. The valve features simple control, fast response, and intrinsic safety, without requiring additional explosion-proof measures.
