These types of valves are designed to allow the liquid to flow in one direction only, preventing reverse flow and assuring process integrity. The two parts of the body are assembled with a standard clamp for guaranteeing fast mantainance operations. These check valves are suitable for vertical or horizontal installation, fully drainable in both execution.
