The Model 753-66 Level Control and Pressure Sustaining Valve with Bi-Level Vertical Float is a hydraulically operated, diaphragm actuated control valve that controls reservoir filling, opening at pre-set reservoir low level and shutting off at pre-set high level.

During filling, Model 753-66 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.

Reservoir or tank level control applications:

  • Prioritizing consumers over reservoir filling
  • Backup for reservoir supply valves
