The Mud gate valve,with superior design features precision workmanship and a proven principle are engineered to meet the harsh drilling requirements in today's oilfield.
The valve conforms to the standard flange dimensions and pressure rating of 2000psi,3000psi and 5000psi working pressure,the norminal size is 2",3",4",and working temperature -20°F to 250°F.
In order to reduce the pressure and displacement fluctuation of the drilling mud pump, an air bag is usually installed on the discharge pipeline. The suction air bag provided by our company has advanced structure and reliable performance, which can make the mud pump achieve the best suction effect and is widely used in petroleum , In the high-pressure pipeline of chemical transportation. This product can also be used as a stabilizer and shock absorber for air extractors.
Long service life: It has a long service life under high pressure;
Easy maintenance: The check valve can be repaired daily without being removed from the high-pressure pipeline;
Strong environmental adaptability: High-pressure check valves are not only used for conventional operations, but customers can also order check valves for sulfur-containing gas operations.
Mud Gate Valve is equivalent to DEMCO model DM series, which is mainly used for mud, cement, fracturing and water service and are easy to operate and simple to maintain. This series of mud gate valve is rising stem, solid gate with resilient seals with superior design and precision workmanship to meet the working request. Designed for dependable, heavy duty performance in abrasive service conditions,BETTER DM mud gate valves are identically to DEMCO DM series in size and fully interchangeable spare parts can be provided.
In-Line field repair ability. For internal parts inspection, or routine maintenance, the bonnet assembly can be quickly removed from the valve body. Parts are replaced as needed, the bonnet assembly re-installed, and the valve is tested and returned to service.
Open and close with ease. Double acting threads and rising stem design mean that opening and closing the gate happens quickly, and with minimal effort to rotate the handle assembly.
