FEATURES

Knife gate valve is also known as knife gate valve, slurry valve, mud valve. Its opening and closing parts are gate. The movement direction of gate is perpendicular to the direction of the fluid. Depending on cutting fiber material blade shaped gate to cut off the medium. The gate board rises and falls in the side guide groove and is pressed on the seat by the bottom lug. If high medium sealing is needed, o-type sealing seat can be selected to achieve two-way sealing. Knife gate valves have small installation space, low working pressure, long service life, simple maintenance.

Suitable Medium:Fresh water, sewage, sea water, acid, etc.

Working Temperature: -20℃~120℃

Application field:Municipal construction, water conservancy projects, oil products, water supply and drainage, water treatment.
