Our 3-piece steel welded ball valve is engineered for high-pressure industrial applications, conforming to DIN standards with a pressure rating of PN 25. Constructed from robust carbon steel, this valve ensures exceptional durability and resistance to corrosion, making it ideal for demanding environments such as oil and gas, chemical processing, and water treatment systems. The welded end connections provide a secure, leak-proof seal, enhancing operational safety and efficiency.Key features include a full port design for minimal flow restriction, a low-torque operation for ease of use, and a blow-out-proof stem for added safety. The three-piece body allows for easy maintenance and inspection without removing the valve from the pipeline, reducing downtime and maintenance costs. This valve is suitable for on/off and throttling services, handling a wide range of media including water, steam, oil, and gas.Material: Carbon steel with welded endsPressure Rating: PN 25 (DIN standard)Temperature Range: -29°C to 200°CConnection Type: Socket Weld (SW)Design: Full bore, three-piece constructionApplications: Industrial pipelines, HVAC systems, and process control
