Coded industrial coupling system developed on the basis of series 21 with above-average flow rate for liquid and gaseous media. Coupling system with single-hand operation. The mechanical coding of the coupling and plug offers a guarantee for avoiding mix-ups between media when coupling, which is complemented by the color coding of the anodised sleeves. - Available on request: • Double shut-off version KASingle Shut-Off coded - 0 coded - 3 coded - 6 coded - 8 Working Pressure*: up to 35 bar Material: • Coupling: Brass • Plug: Brass • Seals: NBR Working Temperature: -20°C up to +100°C (NBR) Flow Rate Air: 310 l/min. inlet pressure 6 bar, pressure drop 0.5 bar Flow Rate Water: 2.7 l/min. pressure drop 0.5 bar KBDouble Shut-Off
