NON-SLAM CHECK VALVES

EXPERT make Non-Slam Check Valves are lift type non return valves used in pipelines to prevent back-flow of the fluid. Designed to fit between two flanges, these valves provide a compact installation when compared to the conventional flanged end check valves.

The Non-Slam Check Valves have short overall length in comparison with the standard flanged end Check Valves. The size and weight are considerably reduced. This offers great advantage for installation, handling, transportation and storing.

Constructional Details
