Cast steel valves are used across the pressure and size range where a forged body would be impractical. Carbon steel WCB covers most non-corrosive process duty; alloy grades cover high temperature and hydrogen service.
Refineries, terminals, power plants and chemical sites run on cast steel gate, globe and check valves in sizes from two to twenty-four inch. Turnarounds replace them in sets, and the removed valves are usually sound enough to rebuild.
We buy cast steel 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 | WCB carbon steel, WC6 and WC9 chrome alloy, C5 and C12 for high temperature, Bolted bonnet and pressure seal |
|---|---|
| Typical service | Refinery isolation, Terminals and pipelines, Power generation |
| What we look at | Size, class, body grade, trim, end connections and pattern. We look at flange faces, body wall, stem and seat. For alloy grades the material certification matters. |
| What to keep | Keep the valve upright and off the ground so the flange faces are not damaged. Keep the bonnet bolting and the handwheel. A cast steel valve dropped on its flange loses much of its value. |
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 the valve upright and off the ground so the flange faces are not damaged. Keep the bonnet bolting and the handwheel. A cast steel valve dropped on its flange loses much of its value.
Where they come from
Industries and services
- Refinery isolation
- Terminals and pipelines
- Power generation
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 valves removed during a turnaround?
Yes, and that is the core of our business. Removed valves with actuators still attached are ideal.
Are alloy cast steel valves worth more?
Generally yes, because the material and the certification carry value. WC6 and WC9 in good condition are strong items.
What about valves with damaged flanges?
They can still be bought as body and bonnet, but tell us. Flange damage is the single most common reason a large valve is rejected.
