Detail Information

Steel lift check valve only allows medium to flow in one direction, in casing of back flow

Characteristics:

1. Steel lift check valve is widely utilized in petroleum, chemical engineering, metallurgy, electricity, etc.

2. The mark on body shows the direction of medium. Upward thrust caused by medium happens to disc. When thrust is higher than gravity of disc, the disc is opened. When the pressure after disc adding with gravity of disc is higher than pressure before disc, the disc is closed to avoid back flow.
