Knife gate Valves specially build to last in abrasive applications with the maximum durability and a great performance, DMMOND valve solutions are engineered and manufactured to become the ultimate Knife Gate Valve solution for handling Slurry media.
DMMOND special top gate sealing concept is designed to ensure full tightness to the atmosphere even for gas or high pressure water applications.
Every design is fully hydrostatically tested at our facilities according to API 598, testing body cavity at 1.5 times the design pressure.
The main characteristic of this Knife Gate Valve design is that it provides a self-flushing concept where not solids can be stacked. As the knife gate closes, flow area is reduced thus increasing flow velocity and turbulences. This turbulences create a self-flushing performance in the inner sleeve groove and ensures a tight sealing when knife gate finally is fully closed.
DMMOND Knife Gate Valves are designed with top quality materials and abrasion resistance special polyurethane able to isolate severe slurries time after time, regardless of how often the valve is actuated.
Our unique one-piece sleeve liner has been performed as a precision molded element with high strength polyurethane to protect the wetted parts, from corrosion and abrasion.
The valve is fully symetrically designed and it’s able to withstand the fluid media in both directions. An specially designed outgoing molded profile among the U-shaped area, ensures a perfect match between the sleeve and the knife gate plate, providing a full tightening performance for the most demmanding applications.
Every design is fully hydrostatically tested at our facilities according to API 598, testing the valve seat at 1.1 times the design pressure in both directions.
The split-body construction and the snap-in sleeve design allows maintenance to be an easy work that can be performed on field. There is no need to return the valve to factory for repair as a fully lined solution can be replaced on-site.
Valve life is increased considerably in comparison with actual slurry knife gate valves with sleeves concept, in addition to its easy maintenance and superior performance we are sure that DMMOND Knife Gate Valves are a great cost-effective solution.
Direct handwheel, Gearbox, Electric actuator, Pneumatic or Hydraulic cylinder actuation types are possible with DMMOND Knife Gate Valve. The design allows actuators to be interchangeable each other even without removing the valve from the pipeline. It most cases, drilled according to ISO 5210 standard.
Our engineering team and manufacturing professionals are proud of every product made, ensuring the most reliable designs and the best manufacturing work to exceed every customer requirements.
Promp delivery solutions, honest customer service and technologically advance valves fully made in Spain, shipped throughout the world.
