Flowrox Slurry Knife Gate valves use a different design approach for sizes from DN 900 to DN 1500. The innovation brought by Flowrox eliminates the knife gate valve’s cylinder tower and instead repositions two actuator cylinders to each side of the valve.
The heavily reduced height of the valve means the center of gravity is positioned lower. Therefore, the knife gate valve is more stable and safer. It is easier to install and requires much less empty room above the valve. All maintenance access points are situated below 2 meters from the ground, making them easily accessible. Similarly, all other connections can be done on or from the ground instead of high in the air.
Another change lies in the knife gate valve’s body. The Flowrox Slurry Knife Gate valve body is now entirely cast in one piece. This means there are no risks for leaking through the body. The new valve construction is simpler and more robust. Less parts mean savings in spare part inventory and maintenance time.
