Product Description

BETTER 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.

Series DM 7500

The BETTER DEMCO DM seat consists of two identical metal wear rings encapsulated in elastomer to form a cylindrical shape with a gate slot and two round ports. The closed gate bears on the downstream wear ring, and the elastomer can provides a drop-tight pressure-responsive seal around the port.

Features and benefits

1. Interchangeable with DEMCO 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 gate and stem are separate parts, which allows the slab style gate to move within the rubber seat in response to the direction and pressure of the drilling mud, or other media, flowing through the valve.
7.Extensive Quality Assurance verification and testing prior to shipment
8.Automation is available for 5,000- and 7,500-psi pressure-rated valves.
9.Exclusive seats design for drop-tight sealing
The Series DM gate valve seats use an unique design to provide a drop
tight shutoff in abrasive and erosive service.
