One-hand air relief couplings with double locking system. Connection: Similar to standard couplings, simply by pressing the plug into the coupling. Disconnection: The first locking mechanism is accessible when the sleeve is pushed back. The coupling valve closes. Air can then then be relieved from the plug side (hose). The second locking mechanism is released by actuating the sleeve again. The coupling can now be disconnected. This system meets the requirements of ISO 4414 and is BIA-compliant (BIA = industrial safety institute).
Operating pressure stems and plugs 0 to 35 bar
