 Product Features: 
 An electric knife slurry valves in accordance with different caliber made of a dark bar and the next shot in two forms (dark bar of DN50 ~ 900mm, the next shot of DN50 ~ 900mm), full-circle design of the DC channel does not exist slag, not jamming. The bottom of the blade processed into a blade-like, soft materials such as fiber, pulp, wood pulp, cut off, at the same time have a good opening and closing the Installed in the upper end of the blade with hard Teflon scraper to prevent dust, gravel and other abrasions substances into the packing box, can significantly increase the life of the blade. The valve plate material selection of stainless steel, grinding and polishing to get the best sealing effect. The compact design, small footprint, light weight, cheap, easy to install, wear-resisting attempts to prevent the measures to improve the ease of maintenance, ease of use and long life, and can be arbitrarily chosen drive. 
 2, valve, filler Han are precision casting, in which the body uses the flange piece casting material according to the user need to use the 304,316,316 L, WCB, 2Crl3, seal with PTFE enhanced PTFE material, resistant to corrosion, wear resistance, non-stick residue. 
 3, the valve plate 5 support points, so that the valve plate good pair. When the valve is turned off, and withstand the back pressure, the valve plate offset. 
 Handwheel, electric knife gate valve can be configured manually zipper, spur gear transmission, bevel gear, pneumatic, and electric. 
 5, within the electric knife gate valve can be made into a V-shaped, triangular, pentagonal channels. V-shaped gate can be used as the adjustment to control the use. 
 , Electric knife gate valve to connect the form of clip-on, flange lug type, sealing metal to metal seal, metal, polyurethane, with enhanced PTFE soft seal. 
 7, electric knives slurry valves for media: gold powder, tailings, pulp, wood pulp, fibers, dust, chemicals, sewage treatment, sedimentation tanks, ore, slag, coal slurry, bitumen, silos, export, fruits, grains , water, mud, and the slaughter house wastewater.
