Product Usage
H41H, H41Y type PN16 ~ PN100 lift check valve is the production process regulation system is an important part of one way to control the flow of medium in the pipeline valve to prevent media backflow.
Features
1. H41H, H41Y-type lifting check valve has the advantages of simple structure, reliable operation, easy maintenance, etc., are widely used in purification equipment, petroleum, chemical, metallurgy, electric power, textile and other production processes
2. When the medium flows into the valve body by the arrow of the valve body, the pressure of the medium acts on the valve disc to generate an upward thrust force, and when the medium thrust force is greater than the valve gravity, the valve is opened. When the valve medium pressure on the role of the valve plus the valve gravity is greater than the pressure on the valve before the valve pressure, the valve closed to prevent the media back
