Our 3-piece stainless steel flanged ball valve is engineered for superior performance in demanding industrial applications. Designed to meet DIN standards and rated for PN 40 pressure, this valve ensures reliable shut-off and control in pipelines handling water, oil, gas, and chemicals. The flanged ends facilitate easy installation and maintenance, while the three-piece construction allows for straightforward disassembly without removing the valve from the line, minimizing downtime and operational costs.Constructed from high-grade stainless steel, this ball valve offers exceptional resistance to corrosion, high temperatures, and abrasive media. It is ideal for use in sectors such as petrochemical, pharmaceutical, food and beverage, and water treatment, where hygiene, durability, and leak-tight sealing are critical. The full port design ensures minimal pressure drop and efficient flow, enhancing system efficiency and reducing energy consumption over time.Key features include:Material: 316 stainless steel for corrosion resistanceDesign: 3-piece, flanged ends per DIN standardsPressure rating: PN 40 for high-pressure applicationsTemperature range: -20°C to 200°C, suitable for various mediaOperation: Lever handle for easy manual control; optional pneumatic or electric actuationApplications: Ideal for shut-off and control in industrial pipelines
