· Interchangeable with DEMCO® mud gate valves.

· In-Line field repairability. 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.

· 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.

· Drop-Tight Sealing. Exclusive seat design provides drop-tight shut-off which is accomplished by metal to rubber sealing.

· 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.

· Extensive Quality Assurance verification and testing prior to shipment.
