Lapar - Model LPB17 -Aeration Damper Butterfly Valve

SHARE

LPB17,aeration butterfly valve, uses the center-line type structure, and the body and disc are welded by steel plates; simple structure, light weight, easy installation, low flow resistance, large circulation; the edge of disc without seal could avoid the influence of high temperature expansion. As a control valve for gas medium, it is widely applied to chemical,building materials, power station, glass industry and so on.

  1. Uses the center-line type structure
  2. Easy installation, low flow resistance, large circulation
  3. Applied to chemical, building materials, power station, glass industry etc
  4. Small flow resistance, high turnover
  5. Temperature up to 1100°C
  6. Sealing performance up to 1%
  7. Medium can flow through the body directly for little resistance and high flow capacity
  8. The body and cover could be made of carbon steel,austenitic stainless steel or special alloy material
  9. 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
  10. Center line-type butterfly valve uses metal sealing seat,which surrounds the disc to reduce the leakage effectively
  1. Body: The body is welded by steel plate for lighter weight .smaller volume,lower cost,and choosing high temperature resistant material can withstand higher
  2. temperature.
  3. V type packing: The sulfur-free flexible v-graphite packing overcomes the faults of normal packing including zero compensation and large deformation,
  4. prolongs the service life, and is able to with stand high temperature.
  5. Seat: The seat ring can reduce leakage and ensure the disc close to 0°.
  6. Disc: The disc is made of steel plate,and stiffeners in both sides can make it withstand deformation due to wind effectively.
  7. Ring: The ring has a location effect,which makes the disc turn in the middle of channel.
