PN10 PN16 JIS Class 150 Knife Gate Valve Cast Iron Ductile Iron Wafer Rubber Seat
Knife gate valve, also known as type knife gate valve, knife gate valve, slurry valve, slurry valve, it is the opening and closing of a ram, the ram of the motion direction and perpendicular to the direction of flow on the blade shape ram can cut fiber cutting medium, sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters, usually for 5 °, wedge type knife gate valve disc can be made into a whole, is called a rigid disc;It can also be made into a small deformation of the gate, in order to improve its process, make up for the sealing surface Angle in the processing of the deviation, called elastic gate.In fact, there is no chamber in the valve body, the gate board rises and falls in the side guide groove, and is pressed tightly 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 valve with small installation space, low working pressure, not easy to pile up debris, low price.
