Model 753-65

Level Control and Sustaining Valve

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, it sustains minimum upstream pressure, regardless of fluctuating flow or reservoir level.
 

Features and Benefits

  • Line pressure driven – Independent operation
  • Bi-Level electric float switch
    • On/off service
    • Low cavitation damage
    • No hydraulic sensing tubes
    • Simplified float installation and setting
    • Reservoir inherent refreshing
  • Solenoid controlled
    • Low power consumption
    • Normally Open or Normally Closed main valve
  • Double chamber
    • Moderated valve reaction
    • Protected diaphragm
  • In-line serviceable – Easy maintenance
  • Flexible design – Easy addition of features
  • Balanced seal disk – High relief flow capacity
     

Typical 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 750-65 Level Control Valve, thereby modifying it to become the Model 753-65 Level Control and Pressure Sustaining Valve.
