A wafer valve fits between two pipeline flanges with bolts passing through or around the body, so it needs no flange of its own. That makes it light, short and inexpensive, which is why wafer butterfly and wafer check valves are everywhere.
Cooling water, HVAC, fire protection, aeration and low-pressure process lines use wafer valves almost exclusively. Construction projects buy spares by the box, and the boxes outlive the project.
We buy wafer valves in any quantity — single items, mixed pallets or whole cribs, including valves that need repair and assemblies that are missing parts. We do not require a clean inventory before reviewing a list.
| Common patterns | Wafer butterfly, resilient and high performance, Wafer check, dual plate and single plate, Lugged variants for dead-end service, Cast iron, ductile iron and stainless |
|---|---|
| Typical service | Cooling water, HVAC, Fire protection |
| What we look at | Pattern, size, body and liner material, and quantity. For new stock we need the part numbers; for used stock we need condition and quantity. |
| What to keep | Keep them boxed with the labels. Wafer valves are identified by part number and size, and loose ones lose value fast. Keep the lever or gear operator attached. |
Patterns and variants
What turns up most often
Variants matter because they change the buyer pool. A standard pattern sells to a rebuilder or a plant with the same service; a specialised trim sells to a much smaller group but often at a higher price. If you are unsure which variant you have, the nameplate or the trim marking will usually say.

How to protect the value
Keep them boxed with the labels. Wafer valves are identified by part number and size, and loose ones lose value fast. Keep the lever or gear operator attached.

- Fire protection
Most of the surplus we see comes from plants that have replaced equipment for a reason that has nothing to do with the valve: a unit was re-rated, a line was re-piped, a control loop was upgraded or a project was re-scoped. The valve is simply the part that has to move.

Read →Questions sellers ask
Do you buy mixed sizes of wafer valves?
Yes, as a lot. Mixed sizes are normal in a stores cleanout.
Are used wafer valves worth anything?
In quantity, yes. Individually, usually not enough to justify a pickup.
What about wafer checks with broken springs?
They are rebuildable, so they still have value. Tell us the condition.
