Our 3-piece stainless steel ball valve is engineered for superior performance in demanding industrial applications. Designed to DIN PN 25 standards, this valve ensures high-pressure resistance up to 25 bar, making it ideal for systems requiring reliable shut-off and flow control. The welding end (SW) configuration provides a secure, leak-proof connection, enhancing system integrity and longevity in corrosive or high-temperature environments.Constructed from high-grade stainless steel, this valve offers exceptional durability and resistance to corrosion, oxidation, and wear. Its 3-piece design allows for easy maintenance and inspection without removing the valve from the pipeline, reducing downtime and operational costs. The full bore design minimizes pressure drop and facilitates efficient fluid flow, suitable for a wide range of media including water, steam, oil, and aggressive chemicals.Key features include:Welding end connections for permanent, robust installationsCompliance with DIN standards for guaranteed quality and safetyThree-piece construction enabling straightforward disassembly and serviceStainless steel material ensuring longevity in harsh conditionsPN 25 pressure rating for high-pressure applications
