Pneumatic Ceramic Knife Gate Valve

Pneumatic Ceramic Knife Gate Valve for Ash, Slurry, Acid. Anti-corosion and wear-resisting,DN50~600Product Description:Ceramic knife gate Valve is suitable for corrosive medium with high hardness of particles (such as slag water), or soft particles in pipeline. The products are widely used in ash, sludge, coal slurry, pulp, sewage and other solid, especially for stone coal system for thermal power plant. Disc and seat sealing surface adopts an advanced ceramics materials technologies for abrasion resistance, corrosion resistance, high temperature resistance. Therefore, this valve has a very high abrasion resistance, corrosion resistance, and good insulation, low thermal expansion.This valve outlet is full circulation without blocking, good abrasion resistance and sealing performance. Opening-load is low, and there's less ash jam phenomenon.This valve has ductile structural ceramic sealing, high mechanical strength, good abrasion resistance, long life durability. The structure is compact and can be installed at any angle. Norminal pressure: PN10~PN25. Applicable temperature:≤250ºC. Actuator Pressure: 0.6~0.8MPa.  It can be designed according to customer's requirement.Material Specification:No.NameMaterialNo.NameMaterial1BodyWCB /CF87NutA194-2H/B82SeatStructural ceramic8Packing GlandWCB/CF83Plate301/3049Cylinder bracketQ235/SS3044Ceramic seal seatStructural ceramic10Stem2Cr13/SS3045PackingPTFE/Flexible graphite11cylinder connecting plateQ235/SS3046StudA193 B7/B812Pneumatic actuatorComponentsMain Dimension (GB/T 9113):DNLPN10(1.0MPa)PN16(1.6MPa)DD1N-MDD1N-M50431651254-M161651254-M1665461851454-M161851458-M1680462001608-M162001608-M16100522201808-M162201808-M16125562502108-M162502108-M16150562852408-M202852408-M20200603402958-M2034029512-M202506839535012-M2040535512-M243007844540012-M2046041012-M243507850546016-M2052047016-M2440010256551516-M2458052516-M2745011461556520-M2464058520-M2750012767062020-M2471565020-M3060015478072520-M2784077024-M33Note: more size, please contact us.     /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
