Product Overview
 Lift check valve for medium and small diameter pipeline pressure, temperature and medium control connected to or cut off the pipeline medium opening and closing device; rely on valve flap weight and fluid pressure automatically stop fluid backflow .
 


Features

1, when the medium flows into the valve body by the arrow of the body, the pressure of the medium acts on the valve flap to generate an upward thrust force, and when the medium thrust force is greater than the gravity of the valve flap, the valve is opened. When the valve medium pressure on the role of the valve with the force of the valve itself is greater than the pressure before the valve pressure on the role of the valve, the valve closed to prevent the media back. 
 2, lifting check valve has the advantages of simple structure, reliable operation, easy maintenance, widely used in purification equipment, petroleum, chemical, metallurgy, electric power, textile and other production processes.
