KIRLOSKAR AIR VALVE
Kirloskar Air Valve: Ultimate Guide to High-Performance Pipeline Protection
Air pocket accumulation and negative pressure are leading causes of pipe bursts, reduced flow efficiency, and structural collapse in water distribution systems. Kirloskar Air Release Valves automatically release trapped air during filling, continuously vent air pockets during operation, and admit air during drainage to protect pipelines from surge pressures.
Designed and tested in full compliance with IS 14845 and BS EN 1074-4 standards, Kirloskar kinetic air valves deliver long-term, zero-leakage security across municipal, industrial, and agricultural networks.
Key Features & Design Benefits
- Dual Orifice Dynamic Design: Combines a large orifice for rapid air venting during pipe filling and a small orifice for continuous air release under working pressure.
- Non-Clogging & Self-Sealing Balls: Precision-engineered rubber-coated or stainless steel floats prevent prematurely blown closures and ensure a tight hydraulic seal.
- Tamper-Proof Cowl: Protected top bonnet shields internal components against external interference, vandalism, and harsh outdoor weather.
- Surge Protection & Vacuum Relief: Rapidly admits air during sudden pressure drops to prevent pipeline collapse caused by negative pressure.
