Model 753-66

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, it sustains minimum upstream pressure regardless of fluctuating flow or reservoir level.  
Product Features & Benefits
  • Line pressure driven – Independent operation
  • Bi-Level hydraulic float control
    • On/off service
    • Low cavitation damage
    • Inherent reservoir refreshing
  • Double chamber design
    • Moderated valve reaction
    • Non-slam closing characteristic
    • Protected diaphragm
  • External installation
    • Easy access to valve and float
    • Easy level setting
    • Less wear and tear
  • In-line serviceable – Easy maintenance
  • Flexible design – Easy addition of features
  • Balanced seal disk – High relief flow capacity
Typical Product Applications

Level Control and Pressure Sustaining
In this elevated reservoir system, pressure to consumers is prioritized over reservoir filling by adding the pressure sustaining feature to the Model 750-66-B Level Control Valve thereby, modifying it to become the Model 753-66 Level Control and Pressure Sustaining Valve.
