ANSI Class 300 flanged ball valves are made of stainless steel and carbon steel. Large diameters can be equipped with worm gear operation. The upper flange meets the ISO 5211 standard, so it can also be used as a pneumatic flange ball valve and an electric flange ball valve.
The valve body is precision cast with high strength. The valve ball is a high-pressure solid ball. The ball valve channel can be polished and is suitable for some special media valves. The paint is sprayed with epoxy resin. The carbon steel ball valve is also durable. Each valve undergoes 1-2 minutes of testing before leaving the factory, and the product quality is high. Simple structure, small size, and light weight.
