Anchor Darling check valves appear across feedwater, condensate, cooling water and process systems in power stations. Many are specified to utility or nuclear quality programmes, which means the documentation is as important as the casting.
When these come out during an outage, they usually come with tags and records. That makes them easier to place than general industrial checks, provided the records travel with the valve.

Inspection points
What decides the price
Documentation
Outage records, material certificates and quality programme paperwork.
Internals
Disc, hinge pin and seat condition. A check valve without internals is a body.
Pattern and rating
Swing, lift and specialty patterns, with the pressure class marked.
What to send
Making the review quick
A wide photograph of the whole unit, a close photograph of the valve nameplate, and the model number if you have it. If there are several identical units, one set of photographs and a quantity is enough.
If the equipment is already separated, keep the parts together and label them as a set. A matched pair is worth more than two orphans.
Questions sellers ask
Do you buy nuclear-grade valves?
Only with full traceability and only as surplus equipment. We make no service or certification claim.
Are these worth more than standard checks?
Generally yes, when the documentation is complete.
