API-6A Demco DM Mud Gate Valves are specifically engineered for the rigorous requirements of oilfield applications. They are designed for dependable, heavy-duty performance in abrasive and erosive service conditions. The mud valves are mainly used for drilling mud circulating system in oilfields to control the flowing and stopping of mud. 

The Demco series DM mud gate valves are offered in two basic pressure classes: The ANSI series valves conform to the standard flange dimension and pressure requirements for ANSI classes 400, 600, 900 and 1500. Except for the 4" class 1500, these valves are designed with economical, double acting threaded stem & gate. The 4" 1500 use the same rising stem design used in the 4" 3000 API series valve. The API series valves conform to the standard flange and pressure requirements for API classes 2000PSI, 3000PSI and 5000PSI. Except for the 4" and larger API 5000PSI, these valves are designed with heavy duty, double acting rising stems. Both series are offered with Threaded, Wutt-Weld, Hammer Union or Flanged end connections. End connection availability varies by size and pressure based on market requirements. Some sizes in the ANSI series are offered with grooved end connections. 

DM mud gate valves can be hard seal or soft seal with pressure up to 7500 PSI. Available in sizes from 2" to 6" (50 mm to 150 mm). All of our DM Mud Gate Valves are fully designed, manufactured, and tested in accordance with API-6A standards. We also produce and supply mud valve repair kits.
