The Swing Check Valve from Gayatri Industries is designed for water and wastewater system applications, offering reliable backflow prevention with a simple, low-maintenance design. Its operation relies on gravity and reverse flow, allowing smooth opening with forward flow and positive shut-off when flow reverses.
Available with metal-to-metal or resilient seats, resilient seated swing check valves are ideal for applications where dirt or particles may be present. Optional external hinge arms with lever weights or adjustable springs help reduce disc slamming and hydraulic shocks, ensuring safe and efficient operation.
