Wafer Lift Type Check Valve
The Wafer Lift Type Check Valve is selected for backflow prevention where a short face-to-face dimension and wafer installation are preferred. Unlike a swing check valve, the lift disc or guided poppet arrangement must be reviewed by flow direction, minimum differential pressure, media cleanliness and installation orientation.
This product page avoids unconfirmed fixed ranges for size, pressure, temperature, leakage class or standard compliance. Those values are confirmed only after Vcore Valve reviews the selected valve model, flange standard and project datasheet.
Wafer Lift Type Check Valve Selection Notes
For a Wafer Lift Type Check Valve, Vcore Valve checks whether the valve will close reliably under the available pressure differential. The Wafer Lift Type Check Valve should not be selected only by pipe size; engineers should confirm media condition, flow velocity, installation direction and whether a spring-assisted design is required.
Engineering Application
This valve is commonly reviewed for water, steam, oil, air and compatible process fluids where compact backflow prevention is needed. Clean service is preferred because suspended solids can affect disc movement, sealing contact and spring performance if the design is not selected correctly.
- Confirm horizontal or vertical installation before selection.
- Review minimum opening pressure and expected pressure drop.
- Check whether the media contains solids or sticky deposits.
- Confirm flange standard, gasket contact and available installation space.
Product Configuration
| Selection Item | Engineering Check | What Vcore Valve Confirms |
|---|---|---|
| Body style | Wafer compact check valve body | Face-to-face dimension and flange compatibility |
| Disc or poppet | Lift movement and guide stability | Flow direction, opening pressure and closing response |
| Spring option | Required for fast closing or vertical service | Material, media compatibility and pressure drop effect |
| Seat design | Metal or soft seal depending on model | Media, temperature and leakage expectation |
| Inspection | Pressure and functional checks per order | Test scope, report format and witness requirement |
Technical Specifications
| Parameter | Selection Guidance | Confirmation Needed |
|---|---|---|
| Nominal size | Project-specific | Pipeline size and flange standard |
| Pressure class | Confirmed by selected body design | Design pressure and test pressure |
| Temperature range | Depends on body, seat and spring material | Normal and upset operating temperature |
| Media | Clean compatible fluids preferred | Fluid name, solids content and corrosion risk |
| Installation | Horizontal or vertical as confirmed | Flow direction and pipe layout drawing |
Comparison Guide
| Option | Best Fit | Selection Note |
|---|---|---|
| Wafer lift check valve | Compact flange-to-flange installation | Good when space is limited and clean media is confirmed |
| Swing check valve | Larger lines with lower pressure drop needs | Requires more installation space and orientation review |
| Dual plate check valve | Compact design with spring-assisted closing | Confirm water hammer and flow velocity requirements |
Pre-Order Checklist
| Checklist Item | Why It Matters | Required From Customer |
|---|---|---|
| Flow direction | Prevents installation error | Pipeline drawing or flow arrow requirement |
| Media condition | Affects disc movement and sealing | Fluid, solids, viscosity and temperature |
| Pressure differential | Confirms reliable opening and closing | Normal pressure and pump conditions |
| Flange standard | Avoids fit-up problems | Flange drilling and gasket type |
| Inspection documents | Aligns QC expectations | Test report, certificate and packing requirements |
Quality and Documentation
Vcore Valve can prepare inspection records, material traceability documents, pressure test records and export packing photos according to the purchase order. Document scope is confirmed before production.

FAQ
Can a Wafer Lift Type Check Valve be installed vertically?
It depends on the selected model, spring design and flow direction. Vcore Valve confirms installation orientation from the datasheet before quotation.
Is this the same as a swing check valve?
No. A wafer lift design uses a compact body and lift movement, while a swing check valve uses a hinged disc and usually requires more installation space.
Why are exact ratings not listed here?
Exact ratings depend on the selected model, material and test standard, so they must be confirmed by datasheet.
What information is needed for selection?
Provide pipe size, flange standard, media, pressure, temperature, flow direction, installation position and required inspection documents.
