Viking Vertical (With Spring) Non-Return Valve (NRV) 50mm (2″) – Brass Check Valve

Viking Vertical (With Spring) Non Return Valve 50mm (2″)

The Viking Vertical Spring Loaded Non Return Valve (NRV) is engineered to automatically prevent reverse flow in water distribution systems. Manufactured from high-quality brass, this 50mm (2-inch) check valve features an internal spring-loaded disc mechanism that closes immediately when flow stops, ensuring reliable backflow prevention and minimizing water hammer effects.

Unlike conventional swing check valves, the spring-assisted design enables faster closing action and improved sealing performance, making it ideal for pressure booster systems, overhead tanks, borewell pumps, hydro-pneumatic systems, plumbing networks, and industrial water lines.

The robust brass construction provides excellent corrosion resistance, durability, and long service life even in demanding operating conditions.
