The STEEL WELDED BALL VALVE SW 3-PIECE • DIN PN 40 is a high-performance industrial valve designed for demanding applications in sectors such as oil and gas, chemical processing, and water treatment. Manufactured to DIN standards with a pressure rating of PN 40, this valve ensures reliability, durability, and optimal flow control in high-pressure systems. Its three-piece welded construction allows for easy maintenance and repair without removing the valve from the pipeline, reducing downtime and operational costs.Constructed from robust carbon or stainless steel, this ball valve features a welded socket weld (SW) end connection, providing a secure, leak-proof seal suitable for harsh environments. The valve’s full bore design minimizes pressure drop and allows for efficient fluid passage, making it ideal for applications requiring minimal flow resistance. Key technical specifications include:Material: Carbon steel or stainless steel, compliant with industrial standardsPressure Rating: PN 40 (DIN), suitable for high-pressure systems up to 40 barEnd Connection: Socket weld (SW) for permanent, robust installationTemperature Range: -20°C to +200°C, depending on material and mediaOperation: Manual handle or actuator-compatible for automationThis valve is engineered for longevity and performance, with a welded ball and stem design that prevents blow-out and ensures safe operation under extreme conditions. It is suitable for a wide range of media, including water, steam, oil, and aggressive chemicals, and is available in various sizes to meet specific pipeline requirements. Ideal for industrial e-commerce platforms, this product offers a reliable solution for engineers and procurement specialists seeking quality valves that meet international standards.
