In combination with Hawle control valves with float control (e.g. model no. 1600, 1601, ...) the float protection tube protects the control unit from strong wave motion in the tank, thus ensuring the proper functioning of the control unit and hence the regulating function of the main valve.
The pilot valves can be easily installed on the drilled installation bracket.
The float protection tube is fixed via pipe clips at the tank wall (observe installation instructions).
