Leader Gun Metal / Bronze Horizontal Lift Check Valve (IS 021 & IS 023)

The Leader Gun Metal / Bronze Horizontal Lift Check Valve provides automated backflow prevention in horizontal piping systems. Built in compliance with IS 778 design standards, this valve features a contoured body profile that reduces pressure head loss while automatically isolating reversed fluid flows.

Key Product Features
