Types of Check Valves: Which One Fits Your Piping System?
Check valves prevent backflow in piping systems, protecting pumps, compressors, and equipment from reverse flow damage. Choosing the right type of check valve is critical for reliable operation and long service life.
Main Check Valve Types
The most common industrial check valves include swing check valves, wafer single plate check valves, wafer dual plate check valves, and lift check valves. Each type is designed for specific flow rates, installation orientations, and pressure conditions.
Selection Guide
| Valve Type | Best For |
|---|---|
| Swing Check Valve | Large diameter, low velocity, horizontal piping |
| Wafer Single Plate Check | Compact installation, general industrial use |
| Wafer Dual Plate Check | Fast closure, water hammer reduction |
| Lift Check Valve | High pressure, vertical flow lines |
