Unique full-open gate type valve mechanism realizes low pressure loss
and high flow rate, which reduces required source air volume.
The flow rate is increased by up to 40% more than that of conventional Cuplas.
During connection and disconnection, the valve is closed, enabling connection/disconnection under zero line pressure.
When the sleeve of socket is returned to its original position, the purge mechanism releases the residual air pressure in the plug, eliminating an unpleasant popping noise and a hose whip back motion on disconnection.
