Heli-Hydrant Application for Fire Fighting.
Beautiful heli-hydrant application of a CLA-VAL modulating float valve with a latching shutoff solenoid.
Controlling valve opening/closing speed does prevent any surge into the upstream water system.
When approaching the heli-hydrant the helicopter pilot remotely triggers the water activation system allowing smooth opening of the CLA-VAL valve Model 129-55 for tank filling.
