Description
The series 21QL is a double shut-off coupling in which both couplings and plugs are fitted with valves. The valves in both the coupling and the plug open when connected. Both valves close virtually simultaneously when disconnected, ensuring minimum leakage loss.
The coupling offers a single handed operation, has extremely compact dimensions and a high flow rate with a multitude of connection options, e.g. with air tools, pneumatic, medical engineering, air supply for respiratory purposes, diving equipment, measuring and control equipment, laboratory installations, chemistry, analysis and dosage engineering.
