Q22HD series pneumatic valve features a unique dual port design, providing both side and top exhaust options to achieve optimized flow performance in limited spaces. This valve meets the international explosion-proof environmental equipment standards for safe operation, and is easy to maintain—a reliable pneumatic control solution compared to traditional valves that are difficult to apply in a hazardous environment.
Features
- Compact pneumatic actuator with dual-threaded ports on the top and side, achieving minimal installation dimensions
- Multiple sealing material options (e.g., NBR or PTFE) for different temperature conditions (80°C/100°C/180°C)
- Non-electric pneumatic control valve suitable for flammable and explosive hazardous areas
- Simple structure, easy maintenance, and quick inspection and replacement for internal components
- Features low-pressure start and high-sensitivity closing, ensuring tight sealing and unrestricted media flow
- Flexible installation at any angle, and reliable dual-direction sealing unaffected by flow direction during operation
- Optimized flow path and exhaust design that minimizes back pressure and enhance response speed
