Check Valve
Describe
Product Usage
 
H41H, H41Y type PN16~PN100 Lifting check valve is one of the important steps in the production process adjustment system. It is a valve that controls the one-way flow direction of the medium in the pipeline and prevents the medium from flowing backward.
 
Features
 
1. H41H and H41Y lift check valves have the advantages of simple structure, reliable operation and convenient maintenance. They 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 as indicated by the arrow of the valve body, the pressure of the medium acts on the valve flap to generate an upward thrust. When the medium thrust is greater than the gravity of the valve flap, the valve opens. When the force of the medium pressure acting on the valve flap plus the force of the valve flap itself is greater than the force exerted on the valve flap by the pre-valve pressure, the valve is closed to prevent the medium from flowing backward.
