Level Control Valve with Bi-Level Vertical Float IR-WW-750-66-B

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.
