HCK4LR Gravity Drain Check Valve

The HCK4 “LR” series of in-line gravity drain check valves are dependable, compact, and rugged. The HCK4 “LR” gravity drain check valves feature a low, wide-opening pressure differential suitable for liquid transfer systems and other low-pressure-drop applications.

In addition, an optional, specially-designed adapter allows direct replacement of existing 3" and 4" Wolf-Linde and HA Phillips gravity drain check valves without repiping.
