Product Summary

Line Break Valve, a kind of valve in industry which closes automatically in occurrence of sudden pressure drop between its upstream and downstream.

Line break valves are belong to compulsory sealed valves. When they are closed, the valves must be pressure to its disc to stop the sealing surface leaking.

when the medium goes through the disc into the valve, operating power need to overcome resistance, which is the friction of the stem and packing and produced by medium pressure of the valve thrust. It need larger force when it is shut, so stem diameter should be large. Otherwise the stem will be bended. In recent years, since the valve sealing emerges, the direction of flow of line break valve disc is shifted into the body cavity.
