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

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.
