Product classification of check valve:
According to the structure, check valves can be divided into three types: lift check valves, swing check valves and butterfly check valves. Lift check valve can be divided into vertical and horizontal. The swing check valve is divided into three types: single-lobe, double-lobe and multi-lobe.
