Double-acting pneumatic pneumatic valve industry valve operating instructions _ pneumatic components factory

Pneumatic pneumatic valve description of double-acting pneumatic pneumatic valve: pneumatic components factory production of double-acting pneumatic valve, pneumatic valve industry is my company according to valve wear powder conveying system, short service life and the development of * * products, dozens of times, life is ordinary valve valve machine has the advantages of open and flexible, sealed performance is good, is coal-fired power plants, mining and other powder and the wear-resisting of ash conveying pipeline valve * *. Double-acting pneumatic pneumatic valve parameters: pressure rating: PN1. 6 ~. 4 mpa range: DN15 ~ 300 mm applicable temperature: - 60 ℃ ~ 560 ℃ double-acting pneumatic pneumatic valve main characteristics: (1) using HVOF supersonic spraying tungsten carbide wear-resisting layer, has high hardness, wear-resisting performance is superior, as well as good collection strength, hardness HV > 1100 10 ~ 15 times higher than hard chromium plating. (2) the seat ring and clamping, reasonable utilize butterfly spring preload ensures a reliable sealing pressure, automatically compensate the thermal deformation, greatly improving the service life of the sealing surface, reduce operating torque. (3) sealing surface has the function of anti particles net mesh, sealing surface in the pneumatic core work will not be damaged, so especially suitable for the working condition of dust. (4) built in stem structure, to ensure the valve stem in using work could never fly out because of the pressure, has better security and rigidity. (5) using all-pass straight flow channel of valve core and the pipe diameter is the same, have zui large flow capacity, zui small flow rate. 6 pneumatic core is just around the valve shaft turn 90 ° can be fully open or close, simple quickly. All landowners standard design the machine according to the fire prevention, anti-static, can be used for a variety of special occasions. Today packing can choose micro PTFE and flexible graphite is used in a variety of different conditions, and can be equipped with vacuum sealing, etc according to the requirement of special seal, with a new generation of double piston gear rack type pneumatic actuators, with compact structure, large output force, and the advantages of action accurate, are interchangeable and electric actuators. Double-acting pneumatic pneumatic valve selection methods: customers when choosing double-acting pneumatic pneumatic valve, must confirm (1) product model (2) nominal size (3) nominal pressure (4) body material (5) trim material 6 connection mode need 7) using temperature actuator type switch or external regulation pet-name ruby whether need attachment whether attending the match solenoid valve explosion. : stainless steel pneumatic regulating pneumatic valve Q641F/H to cut off the pneumatic valve pneumatic valve pneumatic high platform
