Level and Flow Control Valve

The BERMAD Model IR-457-66-U Level and Flow Control Valve with Bi-Level Vertical Float is a hydraulically operated, diaphragm actuated control valve that controls reservoir filling, opening at preset reservoir low level, and shutting at preset high level. During filling, it limits the flow to a maximum preset value.
