Design Featurer

  • Body: The body is welded by steel plate for lighter weight .smaller volume,lower cost,and choosing high temperature resistant material can withstand higher
  • temperature.
  • V type packing: The sulfur-free flexible v-graphite packing overcomes the faults of normal packing including zero compensation and large deformation,
  • prolongs the service life, and is able to with stand high temperature.
  • Seat: The seat ring can reduce leakage and ensure the disc close to 0°.
  • Disc: The disc is made of steel plate,and stiffeners in both sides can make it withstand deformation due to wind effectively.
  • Ring: The ring has a location effect,which makes the disc turn in the middle of channel.

 

Standard

  • Valve body is designed to meet IEC60534-3-1-2001 and GB/T 12221-2005 API609
  • Valve mounting flange shall be per ISO 5211
  • Flange Standard: JB/T79.1-94,JB/T79.4-94. HG20616-97,ANSI B16.5,ANSI B16.47
  • The highest pressure: 1 .OMPa, Temperature range: -196°C ~1100°C
  • Leak standard: ANSI B16.104

Main Feature

  • Medium can flow through the body directly for little resistance and high flow capacity
  • The body and cover could be made of carbon steel,austenitic stainless steel or special alloy material
  • The sulfur-free flexible v-graphite is heat resisting ,we shall ensure the service life of packing is long-term without maintenance by increasing pre-pressure on spring gasket
  • Center line-type butterfly valve uses metal sealing seat,which surrounds the disc to reduce the leakage effectively
