Corrosion and wear resistance

The valve body and sealing surfaces can be made of corrosion-resistant materials (such as 316L, duplex steel, titanium alloy) and hard coatings (such as Stellite), resulting in a longer service life in media containing particles, slurries, or strong corrosive substances.

Bidirectional sealing capability

Maintains a good seal regardless of the direction of media inflow.

Adaptability to high-temperature and high-pressure conditions

The hard seal design (such as stainless steel + hard alloy weld overlay) allows for stable operation at high temperatures (up to 400~550℃) and high pressures.

High-precision shut-off and sealing

The triple eccentric structure ensures virtually frictionless operation of the valve seat and disc during opening and closing. Combined with a metal hard seal or high-performance soft seal, zero or extremely low leakage can be achieved.
