Product description
A 1-½″ ring-type seat insert for Demco DM gate valves: steel seat rings encapsulated in elastomer, of the same insert design as the DM 7500 seat. Cameron lists the DM 7500 itself from 2″ up, so send the nameplate details of the valve and we confirm the fit before quoting. We supply new parts: genuine Cameron (Demco) where you need OEM, or interchangeable aftermarket parts made to the same dimensions — say which on the RFQ.
