Air Valves By Spain Electronotics Corporation (India)

These automatic valves find application in two distinct water main requirements:
1) Discharge of air while filling of pipe and admission of air when the main is being emptied. Here, a relatively large orifice is used, giving a high rate of discharge or in-flow. Buoyant ball in water seals the orifice when the main filling is complete and is held there by the line pressure until such time as the main is shut for emptying.
2) Discharge of air released during operation of main under pressure. Here, the ball leves its seating under pressure when the water in the chamber is displaced by accumulated air.
Standard valves in the IVC range are:
Can be supplied in screwed and flaned ends. The rest are with flanged ends.
