DEMCO Type DM MUD GATE VALVE

Mud Gate Valves, with superior design features precision workmanship and a proven principle are engineered to meet the harsh drilling requirements in today's oilfield. 

VigorPetro DM Series Gate Valves are compatible with the original Cameron DEMCO valves. We can provide both Minor Repair Kit and Major Repair Kit for repair service. Our Mud Gate Valves are designed and manufactured in accordance with the following specifications:-
API 6A    Specification for Wellhead and Christmas Tree Equipment
ANSI B31.3    Chemical Plant and Petroleum Refinery Piping
ASME VIII    Boiler and Pressure Vessel Code
MSS-SP-55    Quality Standard for Steel Castings for Valve, Flanges and Fittings and Other Piping Components
NACE MR-01-75    Sulphide Stress Cracking Resistant Metallic Materials for Oilfield Equipment.

Designed for dependable, heavy duty performance in abrasive service conditions, our DM gate valves are commonly selected for a number of oilfield applications, including:
• Drilling standpipe manifold • Pump manifold block valves • High pressure mud mixing lines
• High pressure drilling system block valves • Wellheads • Well treating and frac service
• Production manifolds • Production gathering systems • Production flow lines

           Hammer Union End                                              Major Repair Kits

The seats are designed to provide a positive, tight shut off every closing cycle, even after long exposure to abrasion and scor-ing. Twin metal wear inserts, encapsulated in an elastomer, form a cylindrically shaped plug made up of a gate slot and two flowports. Once closed, line pressure forces the gate up against the downstream port seals which are tested up to 7,500 psi. The 4 in. 5000 Working Pressure (WP) thru 5 x 4 in. 7500 WP valve has a transparent stem cover which protects and reveals gate open/close position. Stem packing is self-adjusting on all sizes.
