4, knife gate valves can be equipped with decorate the handwheel, manual lasso, is gear, bevel gear drive, pneumatic and electric. 3, valve plate, there are five points, make the valve plate has better since the. Product unique place 1, knife gate valve in accordance with the made non-rising stem and stem diameter is not the same as two ways, Non-rising stem (~ 900 mm, rising stem (~ 900 mm) Dc channel, all round the default no sludge, BuKa resistance. When the valve is in closed condition, and take the back pressure, the valve plate is not skewed. Inside, knife gate valve can be made into 5 V, trilateral, pentagon channel. 8, office temperature: soft tightly closed ( PTFE) ：- 40 ℃ ~ 180 ℃ quality carbon steel: - 29 ℃ ~ 425 ℃ stainless steel: - 40 ℃ ~ 600 ℃ molybdenum chrome vanadium steel: 550 ℃ or less office pressure: 0. 6 to 1. 6MPa。 7, suit to use media: gold ores, tailings, paper pulp, wood pulp, fiber, dust, chemical treatment of waste water, sediment basins, sand, slag, coal slime, asphalt, the export of silo, apple, corn, and sensitive soil slurry, slaughtering plant wastewater, etc. Used in chemical industry, the carboniferous, sugar, sewage, paper and other fields, especially suitable for papermaking industry to adjust and application of throttle on the pipeline. In the upper blade equipped with hard teflon wiper, can avoid dust, grit and scratch things into the stuffing box, can significantly increase the knife plate fixed number of year of survival. Compact default closely, occupying small space, light weight, cheap, easy to install, wear-resisting block processing way to complete, easy maintenance, convenient use and live longer, and could be selected artificially driving devices. Knife plate on the bottom of the processed into the blade shape, in loose soft materials such as fiber, paper pulp, wood pulp have truncated function, open and close at the same time have a satisfactory effect. 2, valve body, stuffing box for precision casting, the inside body sees fit and use the flange type casting, material could be selected according to user requirements, 304, 316, 316 l, WCB, 2 crl3, tightly closed circle sees fit and use of PTFE strengthen PTFE material, corrosion resistance, abrasion resistance, non-stick slag. 6, knife gate valve a petition way of the ear clip Marine valve type, flange type, hard tightly closed tightly closed with a metal to metal, metal for polyurethane, with reinforced ptfe soft tightly closed. Q: PZ943H unique place a: type electric knife gate valve type electric knife gate valve PZ943H electric knife gate Industrial Valves, equipped with many turning type electric device, the valve plate for rectilinear motion from top to bottom, to achieve long-range stem of the valve is opened or closed, and the use of cast steel, stainless steel body material thought fit, size range: (~ DN1000, using temperature: 425 ℃ or less, nominal pressure: 1. 0 to 1. 6MPa。 sheet quality, and the selection of stainless steel, fine grinding polishing treatment can achieve the best effect of tightly closed. V gate can be used as a control. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you.
