Bermad WW750-65 – Level Control Valve



Bermad WW750-65 – Level Control Valve with Bi-Level Electric Float

The Model 750-65 Level Control Valve with Bi-Level Electric Float is a hydraulically operated, diaphragm actuated control valve that controls reservoir filling in response to an electric float switch signal, opening at pre-set low level and shutting off at pre-set high level. The double chamber actuated Model 750-65-B is powered to fully open and close even at very low pressure. It is the first valve of its design in Australia to be compliant and certified for inclusion in municipal water supply and building services.

Reservoir or tank filling applications:

    • Very low supply pressure
    • Low noise generation
    • Energy cost critical systems
    • Systems with poor water quality

Reservoir outflow applications:

    • Distribution routing
    • Sewerage “fill and flush” systems


  • Line pressure driven – Independent operation
  • Bi-Level electric float switch
    • On/off service
    • Low cavitation damage
