High performance wafer double eccentric butterfly valve
Use the double eccentric butterfly valve with the ball sealing surface, with a flexible lip seal, suitable for Reliable sealing and good adjusting performance requiements.
As a result of the design of double eccentric disc, the invention has a tight sealing performance, long Service life. Can be used for quickly cut off or adjust flowing.
Product is suitable for all kinds of industrial liquid and gas in the pipline(including steam) of transfer.
After selected, can also be used for special medium, such as chlorine gas, oxygen, high vacuum, long life, Resistant sulfur and corrosive medium.
Production can also have fire prevention function selection, low temperature type and leakage prevention Selection Connection type can be adopted the wafer type or used in large pipe diameter lug type single flange Design.
Besides according to the standard of ASME B16.5/B16.47, can also according to user requiement, for DIN Standard, JIS and GB standard.
Using a single PTFE seat design, good elasticity, high reliability
1, Lip sealing structure can compensate for temperature and pressure changes
2, Don't need to add "O" ring or matal parts to keep the sealing
3, Bi-direction to no bubble leak sealing test
4, Long service life, easy to maintenance
PEEK sealing seat
PEEK sealing seat have a long life, good performance, the use of a wide range Offset shaft and offset disc design
1, when the seat in opening position or in the middle position doesn't in contact with the disc
2, In the seat up and down position no wear point
3, low torque, small requirment of operator
In 1995 KaiFeng started the design of their own butterfly valve. During this time, we have been consolidated as one of the companies with more stable career, working directly or indirectly with the main valve and fitting users in Africa and Middle East\Australia \Russia\Asia.
