The disconnectable non-pressurized quick coupling socket with valve, DN7.8, series 1600KE, is a high-performance solution engineered for safe and efficient compressed air applications. Equipped with either an external BSPT thread or an internal BSP thread, it ensures versatile integration into various pneumatic systems. Fully compliant with ISO 4414 and EN 983 standards, this coupling minimizes operator risk by preventing hose whipping during disconnection and significantly reducing noise levels. With an impressive flow capacity of 2020 l/min at 6 bar and a working pressure range of 2 to 12 bar, it delivers reliable performance in demanding environments. Its robust construction combines nickel-plated brass, hardened steel, galvanized steel, brass, and stainless steel, guaranteeing durability and resistance to wear. NBR sealing ensures dependable tightness, while the operating temperature range from -20°C to +100°C allows for use in diverse conditions. For maximum safety and longevity, the coupling must be paired with hardened steel plugs from series 25KA and should not be connected directly to pneumatic tools, as vibrations may reduce service life. This advanced quick coupling is the ideal choice for industries seeking safety, efficiency, and long-lasting reliability in compressed air systems.
