LPB17 Aeration Butterfly Valve
Aeration Butterfly Valve, Damper Butterfly Valve
- Uses the center-line type structure
- Easy installation, low flow resistance, large circulation
- Applied to chemical, building materials, power station, glass industry etc
- Small flow resistance, high turnover
- Temperature up to 1100°C
- Sealing performance up to 1%
- 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
- Body: The body is welded by steel plate for lighter weight .smaller volume,lower cost,and choosing high temperature resistant material can withstand higher
- 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.
- 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
