Cast Steel Lift Check Valve H41H-16C

H41H lift check valve is suitable for medium and small diameter pipeline under various pressures, temperatures and media to control the opening and closing device to connect or cut off the pipeline medium; rely on the self-weight of the valve flap and the fluid pressure difference to automatically prevent the fluid backflow.H41H lift check valve is widely used in water treatment, chemical industry, petrochemicals, petroleum, papermaking, mining, electric power, liquefied petroleum gas, food, pharmaceuticals, water supply and drainage, municipal services, electronics, construction, environmental protection, firefighting, heating, central air-conditioning, filtration equipment and other fields. environmental protection, fire fighting, HVAC, central air conditioning, filtration equipment and other fields.

Structural Characteristics

• Lift check valve has the advantages of simple structure, reliable action, easy maintenance and so on.
• When the medium from the valve body arrow shows the direction of flow into the valve body, the pressure of the medium on the valve flap to produce upward thrust, when the medium thrust is greater than the gravity of the valve flap, the valve is open. When the pressure of the medium after the valve on the force of the valve plus the valve's own gravity is greater than the pressure before the valve on the force of the valve, the valve is closed to prevent the medium from flowing backward.
• The sealing surface is not easy to wear, abrasion, better sealing, longer life.
