Aeration Butterfly Valve, Damper Butterfly Valve

Main Feature

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

Design Featurer

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.

Standard

1. Valve body is designed to meet IEC60534-3-1-2001 and GB/T 12221-2005 API609
