Briefly PZ943H electric knife type brake characteristics of pneumatic valve

electric knife type pneumatic brake type pneumatic valve PZH electric knife gate valve, equipped with rotary electric actuator, pneumatic valve plate for rectilinear motion from top to bottom, to realize the remote control of pneumatic valve opened or closed, pneumatic valve body material adopts cast steel, stainless steel, size range: DN ~ DN, using temperature: nominal pressure: ℃ or less. ~。 MPa。 Used in chemical industry, coal, sugar, sewage, paper and other fields, particularly suitable for papermaking industry used on the pipeline to adjust and throttling. Pneumatic product features, knife gate valve according to different made into non-rising stem and stem diameter two forms ( Non-rising stem DN to mm, rising stem DN to mm, all round the dc channel design of sludge, BuKa resistance. Knife plate bottom into the blade shape processing of soft materials such as fiber, paper pulp, wood pulp has cut off function, at the same time has good opening and closing action. In the upper blade equipped with hard teflon wiper, can prevent the dust and scratch sexual material such as gravel into the stuffing box, can significantly improve the blade life. The pneumatic valve material selection of stainless steel, fine grinding and polishing processing can obtain the best sealing effect. Compact design, occupying small space, light weight, cheap, easy to install, wear-resisting prevent measures to perfect, easy maintenance, easy to use and long service life, and can choose which drives. , pneumatic valve, stuffing box are precision casting, including pneumatic valve with flange type integral casting, material can be selected according to user needs, and L, WCB, the Crl, sealing ring using PTFE reinforced PTFE material, corrosion resistance, wear resistance, non-stick slag. , pneumatic valve plate has a strong point, make the pneumatic valve plate has good from to. When the pneumatic valve is closed, and back pressure, pneumatic valve plate is not skewed. Pneumatic, knife gate valves can be furnished with handwheel, manual zipper, is gear, bevel gear drive, pneumatic and electric. Pneumatic valve, knife gate inside can be made into v-shaped, triangle, pentagon channel. V gate can be used as adjusting control. Pneumatic valve, knife gate connection has the wafer, flange type, sealed with a metal to metal hard seal, metal for polyurethane, with enhancement of ptfe soft seal. , applicable medium: gold ores, tailings, paper pulp, wood pulp, fiber, dust, chemical sewage, sedimentation tank, sand, slag, coal slurry, asphalt, bin exports, fruits, grain, cement, the abattoir wastewater, etc. , working temperature: soft seal ( PTFE：- ℃ ~ ℃ carbon steel: - ℃ ~ ℃ stainless steel: - MPa
