The 3-Piece Steel Flanged Ball Valve, designed to DIN PN 25 standards, is engineered for high-pressure industrial applications requiring reliable shut-off and flow control. Constructed from durable carbon steel, this valve offers exceptional resistance to corrosion and mechanical stress, ensuring long-term performance in demanding environments such as chemical processing, oil and gas, and water treatment systems. Its flanged ends facilitate easy installation and maintenance, while the three-piece design allows for quick disassembly without removing the valve from the pipeline.Key features include a full port design for minimal pressure drop, a blow-out proof stem for enhanced safety, and a robust ball and seat construction that ensures tight sealing and leak-free operation. The valve is suitable for handling a wide range of media, including water, steam, oil, and gases, making it a versatile choice for various industrial sectors. It operates efficiently in temperatures up to 200°C and pressures up to 25 bar, complying with international standards for quality and safety.Benefits of this valve include:Easy maintenance and repair due to the three-piece constructionSuperior durability and longevity with carbon steel materialExcellent flow control with a 90-degree operation handleCompatibility with DIN flanges for seamless integrationReliable performance in high-pressure and high-temperature applications
