Overview

Legend model S-614 PVC compression swing check valves are constructed of ASTM D1784 virgin PVC resin. They provide backflow prevention in either the vertical or horizontal postion. Their full flow design eliminates restrictions. The compression-nut end connections permit installtion onto ABS, PVC, or steel pipe and are advantageous in situations where there is considerable vibration. This is paticularly true in the 2" size sewage ejector installations.
