Product Description

Drillmax DEMCO  DM Style Gate Valves (Mud Valves) China BETTER

BETTER DEMCO DM style gate valves are the superior gate valves in the oil and gas drilling industry. Specifically engineered for the rigorous demands of abrasive applications,Designed for dependable, heavy-duty performance in abrasive service conditions, BETTER DEMCO DM gate valves are commonly selected for a number of oilfield applications
The seats are designed for a complete, tight shut off after every closing cycle. Once closed, line pressure forces the gate up against the downstream port sealing it against the rubber seat. BETTER also manufactures 7500 PSI Gate Valves modified from a DM Style 5000 PSI design. Both 5000 PSI and 7500 PSI Gate Valves meet and/or exceed the severe pressure demands of deep well drilling.

Features

1.Interchangeable with DEMCO® 5000 PSI mud gate valves.
2.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.
3.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.
4.Sight lens included on larger sizes. Allows viewing of the stem for determination of gate position, while also protecting the stem from dust and dirt.
5.Drop-Tight Sealing. Exclusive seat design provides drop-tight shut-off which is accomplished by metal to rubber sealing.
6.Bi-directional sealing design. The slab gate connects to the stem with a T-slot design, allowing the gate to float in its slot, to seal against either side of the rubber seat. This allows a pressure responsive seal in either direction of flow through the valve.
7.Extensive Quality Assurance verification and testing prior to shipment.

Connection Type

1. Flanged End Connections 
2. Threaded End Connections
3. Butt Weld End Connections

End = WE) it is important to remove internal rubber parts before welding to prevent damage. Drillmax does
not sell welded bodies with coating since welding destroys the coating.
