• Reservoir level control
  • Prioritizing consumers over reservoir filling
  • Backup for reservoir supply valves


The Model 753-65 Level Control and Pressure Sustaining Valve with Bi-Level Electric Float is a hydraulically operated diaphragm actuated control valve that controls reservoir filling in response to an electric signal. The valve opens at pre-set low level and shuts off at pre-set high level.

During filling, Model 753-65 sustains minimum upstream pressure, regardless of fluctuating flow or reservoir level.
It is the first valve of its design in Australia to be compliant and certified for inclusion in municipal water supply and building services.
