Check Valves are used to stop reversal of a flow in a piping system, e.g. in discharge of all centrifugal pumps. There are many types of check valves and their selection is based on types of fluids, piping configuration and process parameters.
- Swing Check Valve
- Lift Check Valve
- Ball Check Valve
- Piston Check Valve
- Stop Check Valve
- Tilting Disc Check Valve
- Wafer Check Valve
