Valve type
Check Valves
Automatic valves that prevent reverse flow. Selection depends on cracking pressure, orientation, and media conditions.
Common specifications
| Parameter | Typical range / options |
|---|---|
| Types | Swing, lift, dual-plate, silent |
| Sizes | ½" to 48"+ |
| Pressure classes | 150–2500 |
| Materials | CS, SS, alloys |
| Key spec | Cracking pressure / flow orientation |
Always confirm selection against service conditions, standards, and supplier documentation.
Selection considerations
- Confirm installation orientation and flow direction.
- Consider water hammer / slam risk; evaluate silent designs where needed.
- Verify media cleanliness (solids can affect seating).
- Confirm pressure class and temperature requirements.
Typical applications
- Backflow prevention in pump discharge
- Process line protection
- Utility systems requiring one-way flow
- Where reverse flow damages equipment
