Single Union Ball Check Valves
IPEX Single Union Ball Check Valves provide a simple solution for preventing backflow in a Duraplus ABS piping system. The single union design allows easy dismantling of the system for in-line maintenance while guide ribs allow for maximum flow and minimum turbulence, preventing ball sticking and chatter. Just a few psi of back pressure is needed for positive shut off in both vertical and horizontal orientations. Pressure rated to 150 psi at 73oF. Sizes 3/8″ to 3″.
