OEM Air Relief Valve Factory

What are Air Relief Valve?

Air Relief Valve are used in pipelines to automatically vent air or gas from water mains as the line is filled or drained. They allow air pockets to escape while preventing liquid loss, protecting systems from the damaging effects of entrapped gasses.

Characteristics of Air Relief Valve

• Body: Crafted from robust cast iron, steel, or stainless steel, the Air Relief Valve body is engineered to endure system pressures effectively.
• Float: Housing a lightweight float connected to a linkage or mechanism, this component facilitates the automatic opening and closing of the Air Relief Valve.
• Seat: Featuring a resilient synthetic rubber seal, the seat establishes a secure, leak-free barrier to prevent water loss.
• Applications: These valves play a crucial role in air removal during filling (air valves) and air release during draining (vacuum relief valves) operations.
• Operation: As the water level rises in the pipe, air within the rising main escapes through the air valve via OEM Air Relief Valve Factory. When draining, pressure fluctuations trigger vacuum valves to avert collapse.

Applications of Air Relief Valve

• Water Supply – Ensures clean water is not contaminated by backflows from industrial plants, irrigation systems or buildings.
• Swimming Pools – Air Relief Valve protects treated pool water and prevents drainage back-siphoning saltwater into fresh supplies.
• Process & Power Plants – Prevents reverse circulation in steam lines, cooling systems, pumps and critical fluid transfer processes.
• Medical & Laboratory – Backflow prevention safeguards sterilization systems and protects bio-samples in laboratories from contamination.
• Fire Protection – Air Relief Valve checks flow direction in sprinkler systems to guarantee adequate pressure is maintained at each sprinkler head.
• Marine – Keeps ballast systems secure against reversing water currents or accidental suction intakes when loading cargo holds.
