 Outline 
 1, Swing Check Valve 
 Main models: full lining H44F46 and H74F46 unicuspid Swing series and H76F46 double valve Swing series, their structure is: all around the valve seat outside the (sales) axis, embedded in the body and between the formation of a special valve cover groove, opening and closing a flexible, reliable sealing, in addition, H72F46 and H76F46 type check valve is characterized by: in addition to the valve body, valve, the return spring are all corrosion-resistant lining package of fluoride plastic, designed the spring, the valve flap in the low-pressure region can produce more than sufficient sealing pressure to ensure a low pressure area in the valve seal reliability. 

 2, vertical lift check valve 
 Main models are all lined H40F46 type, H42F46 and H72F46 vertical lift check valve, which H40F46 is a new structure, the valve for the dome, their common feature is fluorine valve body along the path to do down the axis of movement. 

 3, lift check valve 
 Main models: full lining H41F46 straight lift check valve, its structure is characterized by: LINING disc perpendicular to the valve inlet and outlet axis for the lifting movement.
