Import Cast Steel Air Release Valve — Buy in Bulk from Supplier in India

The product offered by Leader Valves Limited is a cast steel air release valve designed to vent trapped air from fluid pipelines. It is manufactured from cast steel identified as grade WCB, a material known for durability in water‑handling environments. The valve carries a Class‑150 pressure rating, suitable for typical municipal and industrial water distribution pressures. Its double‑ball mechanism enables rapid air expulsion while maintaining system pressure.

In the valve market, cast steel air release valves of this class commonly meet ISO 9001 quality management requirements, although the supplier’s certification status should be confirmed. Standard temperature operating limits for similar WCB valves range from - 10 °C to 200 °C, and flange connections usually conform to ANSI 150 ratings. Typical sizes run from DN 15 to DN 150, with flow coefficients that suit low‑ to medium‑flow applications. The double‑ball design is preferred for its reliability in water and wastewater networks.

These valves are employed in municipal water supply systems, irrigation networks, and industrial process water loops where air entrapment can cause cavitation or flow inefficiency. Utilities, irrigation contractors and process plant engineers are the primary purchasers.
