Product description
A one-piece seat assembly for 4″ Demco DM mud gate valves rated 2,000, 3,000 and 5,000 psi. Two metal wear inserts are moulded into an elastomer plug that carries the gate slot and both flow ports. The pins locate it in the body, and it seals on both sides of the gate. 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.
