Pneumatic Butterfly Valve Cut Express

Product Description 
I. Product Overview

  Butterfly valve series of quick-cut ALKD673H introducing advanced foreign technology, the three eccentricity metal hard sealing multi-layered structure,Are widely used in medium temperature of ≤ 600 ℃ metallurgical, power, petrochemical and other industrial pipes for the use of cutting fluid, switch time 1 - 5 sec.Three eccentric structure, seat and disc sealing surface plate are stainless steel with different hardness and production, has good corrosion resistance, long service life, product line with national standards GB/T13927-92 valve pressure test.

Second, the characteristics of

1, the valve sealing three-eccentric structure, the valve seat and the butterfly board almost no wear and tear, with more tightening of the sealing concept features.
2, selection of stainless steel ring, both in low-temperature and high temperature cases, both with excellent sealing performance, with a corrosion-resistant, long life and so on.
3, disc plate sealing surface using cobalt-based hardfacing alloy, wear-resistant sealing surface, long service life.
4, the use of large-sized butterflies hang board structure, high strength, large over-current, small flow resistance.
5, drives can be multi-bit (rotation 90 ° or 180 °) to install, user-friendly.
