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

The Cast Iron Kinetic Air Release Valve from Leader Valves Limited is a double ball type valve designed for automatic air expulsion in pressurised piping systems. It has a pressure rating of PN-1.6 and is constructed from cast iron or ductile iron, with ebonite-coated wooden balls to ensure smooth operation and resistance to abrasion. The valve features flanged ends and is available in sizes ranging from 50mm to 200mm, with the listed item CI000094 being a 50mm variant. This design allows for rapid release of trapped air during system startup and prevents vacuum formation during drainage.

The valve body is manufactured to withstand moderate pressure cycles typical in municipal water and irrigation networks. The ebonite coating on the wooden balls provides a seal that resists degradation from prolonged water exposure, a standard practice in kinetic air release valves from Indian manufacturers. Cast iron is chosen for its cost-effectiveness and vibration damping properties, while ductile iron variants offer improved tensile strength where higher mechanical stress is anticipated. The absence of internal springs or moving metal parts reduces maintenance needs in low-sediment environments.

This valve is commonly purchased by water utilities, agricultural irrigation contractors, and industrial plant engineers managing gravity-fed or pump-driven systems. Buyers typically require valves with flanged connections for direct pipeline integration and specify sizes based on pipe diameter and flow velocity. Trade terms are negotiated directly with the supplier; standard packaging is in wooden crates with individual valve protection. Lead time and minimum order quantities are confirmed upon inquiry, as they vary by batch size and production schedule.
