    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.

    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.
