Product description
A replacement seat insert for 3″ Demco DM 7500 mud gate valves. Cameron's bill of materials gives it as AISI 410 seat rings encapsulated in Buna-N; the gate closes between the rings. The insert locks into two AISI 4142 body wear rings, each sealed in the body with its own wear ring seal. 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.
