Our knife gate valves have evolved during decades and stretches from DN 50 (2”) up to DN 1800 (72”). We have a selection of shut-off techniques and materials to choose from. All our products are configurable to your demands.
The knife gate valve offers a full bore and a short face to face. It is often considered to be the optimal isolation valve for liquids with solids or fibers, often having an abrasive characteristic. Sometimes it is also used on dry powder and bulk services or for modulating duties.
Media characteristics and process parameters such temperature and pressure ratio impact on the knife gate valve type you need. If you need assistance in the valve selection, don’t hesitate to contact us or any of our valve experts around the world.
