Vertical lift check valve has the following two characteristics:
1. Vertical check valve has flange and wafer types, with a simple structure, few parts, light weight and other features. Flange vertical check valve is mainly used in various working conditions of preventing the media backflow.
2. When the flange vertical check valve used as vertical installation, it will not set the spring. Using the disc weight and backflow pressure to achieve the check effect.
