Model 750-66-B

Level Control Valve

The Model 750-66-B Level Control Valve with Bi-Level Vertical Float is a hydraulically controlled, diaphragm actuated, double chambered control valve. The valve is hydraulically powered to fully open at pre-set reservoir low level, and to shut off at pre-set high level regardless of valve differential pressure.
 

Features and Benefits

  • Line pressure driven – Independent operation
  • Bi-level hydraulic float control
    • On/Off service
    • Low cavitation damage
    • Suitable for low quality water
    • Inherent reservoir refreshing
  • Double chamber
    • Full powered opening and closing
    • Decreased pressure loss
    • No throttling noise
    • Non-slam closing characteristic
    • Protected diaphragm
  • External installation
    • Easy access to valve and float
    • Easy level setting
    • Less wear and tear
  • Balanced seal disk – High flow capacity
  • In-line serviceable – Easy maintenance
  • Flexible design – Easy addition of features

Typical Applications 

Infrastructure Reservoirs
Optimal design of reservoir systems requires specifying a level control valve that reduces pumping costs by minimizing the extra pumping pressure required to operate standard valves.
Even at very low pressure, the Model 750-66-B ensures full opening, maximum flow capacity, and secure closing. It should be included during the system design phase or with changing needs.
