Hastelloy Butterfly Valve

Both high-performance and triple-offset GMK Hastelloy butterfly valves are available. As a novel kind of butterfly valve, the Hastelloy high-performance butterfly valve takes the best features from existing designs. This butterfly valve has great cutting-off performance and longevity because the sealing surface of the plate is a spherical arc body and the sealing mechanism creates a true dynamic seal via the pressure of the system. It’s portable, lightweight, versatile, and simple to manufacture, fix, and maintain. Metal-to-metal seals are used in the construction of Hastelloy triple offset butterfly valves, which allow for reliable sealing at temperatures ranging from cryogenic to superheated.

Therefore, in the area of big port warp regulation, the GMK Hastelloy butterfly valve has a low flow resistance at full openness and sensitive flow control between roughly 15 degrees and 70 degrees. The butterfly valve already dominates the market and will continue to do so in the future. Many different types of media, including those containing suspended solid particles, may be handled by a Hastelloy butterfly valve because of its wiper-activated plate movement.


  • In situations such as chloride etc. oxidized acid, in habitats such as the oxidant reducible acid, and in environments such as the nitration mixture, etc. with both reducible acid and oxidized acid, it demonstrates exceptional performance in terms of its resistance to corrosion.
  • One of its most notable qualities is the excellent resistance to corrosion it has in situations with high oxidability and reducibility in corrosive media. This is one of its most impressive qualities.
