Product Description

 

Product Description

A73INF Dome type butterfly valve has a logic clear inflating model which supply compressed air to back of seat when the valve close and release compressed air before the valve opening. For abrasive materials like Lithium battery materials, boiler bed sand and limestone, even sticking powder, the inflatable seat can allow solids existing between seat and disc without effecting to sealing. Extra size of solids will be wiped off by the valve construction, sealing are well assured and well protected.

Since there is no friction between the disc and the seat when the valve is operated, meanwhile the valve stem is behind the seating ring instead of go through seating ring like traditional inflatable seat butterfly valve, a A73INF Dome type butterfly valve can reach a life of more than three million cycles, providing contact wear compensation even when the valve seat or ball is severely abraded by material.

For slurry, bulk powder, particles, irregular solids, adhesive powder, gas and gas powder, the A73INF Dome type butterfly valve ensures the reliability of system operation and increases valve life by magnitude, greatly reducing impact of valve stop or replacement on material production.
