I. Introduction
I plant a single eccentric by streamlined design flange butterfly valve, butterfly valve to overcome the friction of ordinary large, difficult to remove, and large water loss defects. Can be widely used in water supply and drainage, construction, air conditioning, sewage, petroleum, chemical, pharmaceutical, textile, water pipelines and other systems for cut-off and regulation.
Second, characteristics
1 disc use streamlined, truss design, can greatly reduce the fluid resistance.
2, sealing butterfly valve seat directly on the board, do not remove the valve stem can be replaced.
3, single eccentric structure, reduces friction sealing seat.
4, the overall epoxy powder paint, as long as the replacement of the valve seat seal material can be applied to different media.
Third, the technical parameters
Pressure rating: 1.0MPa, 1.6MPa
Body Pressure: 1.5MPA, 2.4MPa
Seal test: 1.1MPa, 1.76MPa
Operating temperature: O ~ 80 ℃
Suitable medium: water, gas
