DN50 PN16 Stainless Steel Flange Ball Valve Casting

The DN50 PN16 stainless steel flange ball valve casting (Model F6128) is a high-quality investment casting designed for industrial fluid control. The material grade CF8 (304 stainless steel) ensures good corrosion resistance and mechanical properties, suitable for moderate corrosive environments. The casting is pressure-rated to PN16 (16 bar), making it compatible with European standard piping systems.

This product is optimized for ball valve assembly, featuring a precision-machined spherical cavity to ensure smooth rotation of the ball and reliable sealing. The flanges adhere to EN 1092-1 or DIN standards, ensuring compatibility with European pipeline networks. The casting process minimizes porosity and inclusions, critical for high-pressure applications.

Quality control measures include hardness testing, dimensional inspection, and air-tightness tests. It is commonly used in HVAC, general industrial fluids, and low-corrosion chemical services.
