Air Vent Valve

Approx. Rs 4,499 / NumberGet Latest Price

Automatic Air Valves are essential components for fluid systems that continuously accumulate air. These valves are designed to automatically release trapped air from pipelines and tanks without manual intervention, preventing air pockets that can reduce flow efficiency, increase energy consumption, or cause water hammer. Compact and reliable, they ensure optimal system operation across water, wastewater, and industrial process lines.

• Valve Type: Single / Double Orifice Automatic Air Release Valve

• Body Material Options:
  ➤ Ductile Iron, Cast Iron, Stainless Steel (SS304 / SS316), Bronze

• Float Material: SS304 / SS316 / Polypropylene

• Size Range: ½" to 4" (DN15 to DN100)

• End Connections:
   Flanged – ANSI B16.5 / DIN PN10–PN25
   Screwed – BSP / NPT

• Working Pressure: 0.2 bar to 16 bar (up to 25 bar on request)

• Temperature Range: -10°C to +130°C (higher on request)

• Orifice Types: Small Orifice (continuous release) / Large Orifice (initial priming & draining)

• Seal Options: EPDM, NBR, Viton

Continuous Air Removal
Automatically vents small volumes of accumulated air during system operation

Large Air Discharge Capability
Releases large air volumes during pipeline filling or draining to prevent vacuum formation

Compact, Lightweight Design
Easy to install on new or existing pipelines and equipment

Corrosion-Resistant Internal Components
Stainless steel or composite floats resist wear and chemical damage

Drip-Free Performance
Tight sealing ensures no water leakage under operating pressure

Low Maintenance
Self-operating with minimal need for inspection or servicing
