Kranti Dual Plate Check Valve
Reliable backflow prevention valve
The Kranti Dual Plate Check Valve is a compact, non-slam non-return valve designed to prevent reverse flow in industrial pipelines. Its wafer-type design makes it significantly lighter and smaller than traditional swing check valves, reducing the need for heavy pipe supports. The valve features spring-loaded plates that initiate closure as flow velocity decreases, effectively eliminating water hammer and protecting pumps from rising mains. Built with a Cast Iron body and internal components like SS304 flaps and Stainless Steel springs, it ensures long-term durability and a leak-proof seal.
