X-S10-140-F10+F12-JH Pneumatic High-Temperature Ball Valve, FIG150 Pneumatic Hard Seal Flange Ball Valvefeatures nickel-based alloy spray welding on the surface of the ball and the valve seat sealing surface, hardening the sealing surfaces. The valve ball and seat are ground to achieve a perfect fit, ensuring a high sealing grade. During operation, the valve ball and seat can scrape off foreign matter adhering to the ball surface, providing a self-cleaning function. Suitable for high-temperature, high-pressure applications involving granular powders and slurry fluids.

Performance Characteristics
Metal hard seal ball valves can withstand temperatures up to 538°C, making them suitable for high-temperature steam or other media applications.
Due to the nickel-based alloy spray welding on the valve ball and seat surfaces, metal hard seal ball valves offer high hardness and can be used in environments with granular dust.
Product Advantages
Excellent wear resistance: The valve core of the hard seal ball valve is spray-welded with alloy steel, and the sealing ring is overlay welded with alloy steel, resulting in minimal wear during operation.
Superior sealing performance: The sealing of the hard seal ball valve is manually ground until the valve core and sealing ring achieve a perfect fit, ensuring reliable sealing.
Easy operation: The bottom of the sealing ring in the hard seal ball valve uses a spring to keep the sealing ring tightly pressed against the valve core, making operation very smooth when external force exceeds the spring's preload.
Long service life: Widely used in petroleum, chemical, power generation, papermaking, aviation, and other industries, as well as in daily life.
