Electric knife gate valve PZ943H Electric knife gate valve, with multi-turn electric devices, the valve plate for up and down linear movement, remote control valve to open or close the valve body made of cast steel, stainless steel, diameter range: DN50 ~ DN1000, temperature: ≤ 425 ℃, nominal pressure: 1.0 ~ 1.6MPa. Used in chemical, coal, sugar, sewage, paper and other fields, especially for the paper industry in the pipeline for regulation and throttling use. Features 1, blade-shaped pulp valve made in accordance with different caliber dark rod and rod in two forms (dark rod DN50 ~ 900mm, bright rod DN50 ~ 900mm), full circular DC channel design does not slag, no jamming. The bottom of the blade is processed into a knife-edge shape, the soft material such as fiber, pulp, wood pulp has cut off function, at the same time have a good opening and closing effect. In the upper edge of the blade is installed a hard Teflon scraper to prevent dust, gravel and other abrasives into the stuffing box, can significantly increase the life of the knife. Valve plate made of stainless steel, fine grinding and polishing treatment can get the best sealing effect. Compact design, small footprint, light weight, low cost, easy to install, wear-resistant anti-blocking measures to improve, easy maintenance, easy to use and long life, and optional drive. 2, the valve body, packing culvert are precision casting, of which the valve body flange casting, the material can be used according to user needs selection 304,316,316 L, WCB, 2Crl3, PTFE PTFE ring reinforced PTFE material, resistant Corrosion, wear-resistant, non-stick slag. 3, the valve plate has 5 support points, the valve plate has a good self-aligning. When the valve is closed, and withstand back pressure, the valve plate does not shift. 4, blade-shaped slurry valve can be configured hand wheel, manual zipper, spur gear transmission, bevel gear transmission, pneumatic and electric. 5, Knife-shaped slurry valve can be made internally V-shaped, triangular, pentagonal channel. V-type gate can be used as a regulator control. 6, Knife-shaped slurry valve connection in the form of clip-on, flange lug, sealed metal to metal hard seal, metal on the polyurethane, with enhanced PTFE soft seal. 7. Applicable medium: gold ore powder, tailings, pulp, wood pulp, fiber, dust, chemical treatment sewage, sedimentation tank, ore, slag, slime, bitumen, silo exports, fruits, cereals, grout, slaughter Plant wastewater and so on. 8, Working temperature: PTFE: -40 ℃ ~ 180 ℃ Carbon steel: -29 ℃ ~ 425 ℃ Stainless steel: -40 ℃ ~ 600 ℃ Chrome molybdenum vanadium steel: ≤550 ℃ Working pressure: 1.6MPa
