Product description
A replacement gate for 3″ Demco DM mud gate valves rated 7,500 psi — the sliding closure that shuts off against the seat. The gate and seat wear as a pair, so we usually quote them together, or as a repair kit. 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.
Gates we have photographed at this size

Each row is a gate we have photographed; the series is from its stamp or the supplier's listing, and “Not marked” means neither states it. Black gates are typically QPQ-nitrided alloy steel, the DM 7500 finish; nickel-plated steel is the standard DM 2000–5000 gate.
