Smartflow Dry Break Couplings

Smartflow’s range of dry break couplings are aimed to aid safe, efficient and environmentally friendly transfer of fluids in safety critical, aggressive environments. Making completely Spill-Free connections and disconnections with minimal parts and no additional valves required mean the Smartflow systems can save the customer time and money.

How do they work?

The couplings use a simple integrated poppet system, that activates as the female (Hose) unit is connected to the male (Tank) unit.

As the female coupling easily fits over the male adaptor, it is then twisted clockwise a 1/3 of a turn and locks in place – opening the integrated poppets in both halves and releasing the flow. The reverse anti-clockwise turn will unlock the couplings and instantly shut off flow with zero (well very, very close to) spillage.
