一．Product Introduction
H41H, H41Y type PN16~PN100 lifting steel check valve is one of the important links in the production process adjustment system. It is a valve that controls the one-way flow of media in the pipeline to prevent the backflow of media.
二.Product Features
1. H41H and H41Y lifting steel check valves have the advantages of simple structure, reliable operation and easy maintenance. They are widely used in purification equipment, petroleum, chemical industry, metallurgy, electric power, textile and other production processes.
2.When the medium flows into the valve body from the direction shown by the arrow of the valve body, the pressure of the medium acts on the disc to produce upward thrust. When the thrust of the medium is greater than the gravity of the disc, the valve opens.When the force of the medium pressure behind the valve acting on the disc plus the gravity of the disc itself is greater than the force of the pressure before the valve acting on the disc, the valve is closed to prevent the medium from flowing back.
