American standard butterfly valve is a new generation of high performance products, which was developed by my company engineering and technical personnel.

Its performance is advanced level in the domestic and foreign, are widely used in low pressure, medium pressure and high pressure, iron and steel metallurgy, petroleum, chemical, electric power and other industrial piping for truncating or adjusting the medium flow.

The valve adopts the three-dimensional eccentric oblique conical seat seal, and seal butterfly plate adopts the new metal with elastic material layer, flush mounting on the disc and seat.

Using butterfly plate's oscillation to press tighly seal, so the sealing's friction resistance is small, and close tightly for reliable sealing. And for ensuring that the sealing surface completely out of contact and is not damaged when open.

The butterfly valve structure exclude other types' faults which can't be completely sealed, and under the high temperature can normal use, and overcome the fault of the other type of valve which easily leakage once thermal expansion in high temperature.

According to medium requirements, choose different sealing material, to ensure the sealing wear resistance, corrosion resistance, long service life.
