Highlight: Stainless triple offset butterfly valve
Product introduction:
The triple-offset metal hard-seal butterfly valve features an integrated structure for the valve body and seat, with the seat's
sealing surface overlaid with temperature and corrosion-resistant alloy materials. A multi-layer soft-laminated sealing ring is
fixed on the valve disc. Compared with traditional butterfly valves, this type offers advantages such as high-temperature
resistance, lightweight operation, frictionless opening/closing, and sealing compensation through increased torque of the
drive mechanism during closure, which enhances sealing performance and extends service life. It has been widely applied in
petroleum, chemical, metallurgical, hydropower, and many other industries.

Product features:
1. The hard-sealed butterfly valve adopts a triple-offset hard-sealed structure, with minimal wear between the valve seat
and butterfly disc, and features a sealing function that tightens as it closes.
2. The sealing ring is made of stainless steel, combining the dual advantages of metal hard sealing and elastic sealing. It
demonstrates excellent sealing performance in both low and high temperatures, along with characteristics such as
corrosion resistance and long service life.
3. The sealing surface of the butterfly disc is overlay-welded with hard alloy, making it wear-resistant and extending its
service life.
4. Large-sized butterfly discs adopt a truss structure, which offers high strength, a large flow area, and low flow resistance.
5. According to user requirements, the hard-sealed butterfly valve can be designed with a bidirectional sealing function. It
is not restricted by the medium flow direction or spatial position during installation, allowing installation in any direction.
