This valve serves as the essential exhaust protection system for fluid pipeline networks.
- Automatic Air Exhaust: Efficiently removes air during pipeline filling and long-term operation, preventing air blockage and optimizing water flow efficiency
- Biogas & Harmful Gas Removal: Safely discharges gases produced by organic decomposition in sewage pipelines, preventing pipeline bursting and odor leakage
- Water Hammer Protection: Reduces risk of pressure surges in municipal water supply mains after exhaust operations
Manufactured from durable ductile iron with anti-corrosion spray treatment, designed for pressure resistance and corrosion protection in both buried and open-air environments. Features bottom flange for simplified pipeline connection.
Consists of metal mesh (porous structure) and valve cover with float + sealing mechanism. The float automatically rises to close exhaust port when pipeline is full of water, and drops to allow gas discharge when pipeline is empty.
- Municipal Water Supply: Urban water supply mains, community secondary water supply pipelines
- Sewage Pipe Networks: Sewage treatment plant water inlet pipes, urban drainage mains
- Water Conservancy Projects: Irrigation channels, reservoir water pipelines
