Check Valve Features and Classification

Check Valve FeaturesThe main features of the check valve include automated opening and closing, prevention of medium backflow, excellent sealing performance, wide applicability, and diverse structural design.

Check Valve Classification：

1. Vertical Lift Check ValveCheck valve with a disc that slides along the vertical centerline of the valve body

   The level-mounted check valves are installed on horizontal pipelines, and spherical disks can be used as the valve discs for high-pressure small-bore check valves.

   The body shape of the swing check valve installed horizontally is the same as that of a gate valve (can be used interchangeably with a gate valve), hence it has a higher fluid resistance coefficient.

     2.Swing Check ValveCheck valve with a disc that rotates around a pivot shaft

Check valves with disc valves rotating around a pivot shaft and swing check valves are more commonly used.

     3.Check ValveCheck valves, with their disc-shaped structure rotating around a pin within the valve seat, are simple in design; they can only be installed...

Sealing is subpar on horizontal pipelines.
