Flow Rating

Model BPCV-50FD. Cv Factor 6.7. Back pressure check valves (BPCVs) are spring loaded check valves. When properly sized and installed, they are designed to allow flow in one direction only. These valves are recommended for all inflowing lines when outward flow is never required. Back pressure check valves should be installed as close to the tank as possible, with the stem pointed inwardly toward the tank.
