Demco
Gate Valves are specifically used in high-pressure
mud applications and other corrosive services.
We manufacturer the spares of these valves, which are
Seats, Gates, Stem, Screw etc. Demco Gate Valve
Seats are designed for tight shut off after exposure to
abrasion and erosion. These Seats consist of two
identical metal wear rings encapsulated in rubber to
form a cylindrical shape with a gate slot and two round
ports. The closed Gate bears on the downstream wear ring
while the rubber provides a drop tight, pressure
responsive seal around the port. This seal is fully
effective even when the Gate and the Seat ring are
scored or abraded. The cylindrical assembly fits into
the matching body cavity and is expanded outward towards
the valve ports by the bonnet, which engages pin
extensions from both wear rings. This seals the Seat
against the body, around each valve port. |
