Our 3-piece stainless steel threaded ball valve is engineered for high-performance industrial applications requiring durability and reliable shut-off. Designed to meet DIN standards and rated for PN 25 pressure, this valve ensures leak-proof operation in demanding environments such as chemical processing, water treatment, and oil and gas systems. The threaded ends facilitate easy installation and maintenance, while the 3-piece construction allows for quick disassembly without removing the valve from the pipeline.Constructed from corrosion-resistant stainless steel, this ball valve excels in handling aggressive media and extreme temperatures. Key features include:Full port design for minimal pressure drop and high flow efficiencyFire-safe design with anti-static functionality for hazardous conditionsBlowout-proof stem and reinforced seating for enhanced safetyCompatibility with a wide range of fluids, including steam, gases, and corrosive liquidsIdeal for both on/off and throttling services, this valve offers superior longevity and reduced maintenance costs. Its robust build and compliance with international standards make it a preferred choice for engineers and procurement specialists seeking reliability in critical operations.
