LIFT CHECK VALVE

ㆍDESCRIPTION

Have an advantage over most other types of check valves in that they need only a relatively short lift to obtain full valve opening. The lift check valve uses a freemoving closure element that is placed above the seat. It prevents backflow and maintains pressure. The lift check valve is recommended to install in horizontal piping lines because the disc is pushed up by the flow until the flow reverses when gravity and down stream pressure close the closure element against the seat.
