quick couplings welding lines

Safety sockets for connection to bottles or network on welding lines

Mounted on the exit pressure regulator, the Stäubli SUPER-PARFLAM couplings ensure the installations are protected with 3 integrated safety devices: gas non-return valve, flame arrestor, and the thermal cut-off valve. Gas flow is stopped automatically on disconnection. For safety operations, the geometrical locks remove any risk of swapping the circuits. The quick-release function means the lines can be connected and disconnected in just one movement and the couplings can be rotated, ensuring that the button is always accessible.
