Full Blow Coupler
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 then 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.
