Knife gate valve,Knife type slurry valve, it is the opening and closing is by disc, the disc of direction perpendicular to the direction of flow,On the blade shapedisc can cut fiber cut off the medium,Sealing face has two side, two face sealing one is wedge, the wedge Angle vary with the valve parameters usually 50 angle , wedge type knife gate valve disc can be made into a whole, is called a rigid disc;Can make it produce a trace of deformation of disc, in order to improve the manufacturability, make up for the sealing surface Angle in the process of our processing deviation, this damper is called elastic disc.Actually does not exist in valve body, disc guide groove inside the elevator, and from the bottom of the lugs compression on the seat, if you need to achieve high sealing medium, o-type sealing seat can be used to realize two-way sealing.Knife gate valve has a small installation space, working pressure is low, not easy to pile up sundry, the price also very low.
 when knife gate valve was closed, sealing surface can only rely on medium pressure to seal, it  means should be depend on medium pressure, the disc will be go to the other side of the seat sealing surface to make sure  the seal face sealing , we called it self sealing.Most of  knife gate valve is made mandatory sealing, when the valve is closed, to rely on outside force  the disc pressure to the seat, to ensure the sealing surface of sealing shall be installed in the pipeline.
1.Can promote the disc sealing surface, can shave their sticky on the surface of the sealing, automatic removal of impurities;
2.it have shut off or turn on, also have throttling of double efficacy;
3.Ultrashort structure length, save material, reduce pipeline system as a whole weight; 
4.Take up a little  space , can effectively support the pipeline strength, reduce the pipeline vibration; 
5.Triangular support save the  materials, to guarantee the  mechanical properties; 
6.Body of the guide block make the disc right movement and to make sure the  effective seal;
7.Suitable for different configuration at any Angle in the pipeline. 
Structure & Theory
(1)BODY,(2) Support (3)Hand wheel:Ductile cast iron (4)Disc:Stainless steel (5)Rubber gasket   (6)Four fluorine orifice  (7)Packing:Teflon ring(8)Gland:stainless steel  (9)Lead screw,(10)Stem nut :Stainless steel (11)Cap:35# 
Specification
1.For nearly and remote control,according to the requirements of the users to realize remote location and remote control. 
2.Light weight: valve body is carbon steel,weight is lighter than the normal gate valve 20%-30%,install and repair very convenience. 
3. Used this kind of gate valve can improve the closing of the conveying pipeline, system sealing performance and maximize prevent leakage, to improve the production efficiency, protect the environment will play a positive role in promoting.. 
4.Sealing surface using high wear resistance,corrosion resistant ceramic material, used  the Mosaic technology, high corrosion resistance, good wear resistance, so as to make the valve life is long, cost performance than ordinary valves increase 10 times.
