The EWO EW-411 SAFETY rotary quick coupling socket with shut-off valve, DN 7.4 with hose end, is a high-performance solution designed for maximum operator safety and efficiency. Its innovative one-sided shut-off system allows disconnection without pressure, while the integrated push-button mechanism ensures controlled venting before release, eliminating recoil and meeting ISO 4414 and EN983 safety standards. The two-step operation guarantees reliability: the first press vents the coupling with the plug secured, and the second press safely releases it. Thanks to the rotatable socket, the button can be positioned for optimal accessibility even under pressure, making daily use more convenient. Engineered for durability, the socket combines galvanized steel, anodized aluminum, and nickel-plated brass, with stainless steel springs and balls for long-lasting performance. Delivering an impressive flow rate of 1960 l/min at 6 bar with a working pressure up to 16 bar, it operates flawlessly in demanding conditions from -20°C to +100°C. Compatible with EURO DN7.2 steel plugs, it offers versatility and reliability across industrial applications. On request, the socket can be customized in various colors or manufactured entirely from stainless steel, providing both functional and aesthetic flexibility. Sealed with NBR for secure operation, this coupling is the ideal choice for professionals seeking safety, efficiency, and robust quality in compressed air systems.
