Hard seal ball valve
The Hard Seal Ball Valve utilizes a metal-to-metal sealing structure with precision-machined and hard-coated ball and seat surfaces. Designed for severe operating environments, it offers superior wear resistance, high-temperature capability, low leakage rates, and dependable shutoff performance for demanding industrial applications involving steam, slurry, and abrasive media.
Hard seal ball valve
The Hard Seal Ball Valve is engineered for critical applications where conventional soft-seated valves cannot withstand extreme temperatures, pressures, or abrasive media. Its metal-seated design incorporates advanced hard-facing technologies such as Stellite, tungsten carbide, chromium carbide, or other wear-resistant coatings to ensure outstanding durability and sealing integrity.
Available in floating and trunnion-mounted configurations, the valve provides reliable operation in power plants, petrochemical facilities, mining operations, metallurgy, and chemical processing industries. The robust construction significantly extends service life while reducing maintenance costs.
Our Hard Seal Ball Valves are manufactured and tested according to international standards:
