The high-performance hard sealed butterfly valve adopts a metal to metal sealing structure, which is resistant to high temperature and high pressure
○ Nominal diameter: DN50~DN1200mm
○ Nominal pressure: PN6~PN160bar
○ Applicable media: water, oil, gas, etc
○ Operating temperature: -196 ° C to+550 ° C
○ Connection methods: clamp type, flange type, welding
Valve body material: cast steel, stainless steel, chromium molybdenum steel, duplex steel
○ Butterfly plate material: ductile iron, stainless steel 304316, 1.4529
○ Sealing form: Double eccentric, triple eccentric metal hard seal
○ Operation mode: manual operation of worm gear, pneumatic, electric
○ Adopting a metal hard sealing structure, it is resistant to high temperature and high pressure, and suitable for harsh working environments
○ Precise grinding and matching of valve seat and butterfly plate, wear-resistant and anti erosion, long service life
○ The valve body flow channel is smooth and unobstructed, with low flow resistance, effectively reducing system energy consumption and pressure loss
○ Low opening and closing torque, flexible operation, supports multiple driving modes such as manual, pneumatic, electric, etc
○ Excellent thermal cycling stability, able to maintain sealing reliability under frequent temperature changes
○ Oil and gas pipelines: used for cutting and regulating high-temperature and high-pressure oil and gas media, meeting strict sealing requirements
○ Thermal power plants: applied to high-temperature and high-pressure pipelines such as main steam, feedwater, and flue gas and air systems
○ Chemical and coal chemical equipment: suitable for process pipelines containing particles, corrosive or high-temperature reaction media
○ Metallurgical industry: used for controlling high-temperature abrasive media such as blast furnace gas, hot air, and dust removal systems
○ Large scale centralized heating system: achieving reliable cutoff and regulation functions in high-temperature hot water or steam pipelines
