IR-453-66

Level Control and Pressure Sustaining Valve

The BERMAD Model IR-453-66 Level Control and Pressure Sustaining Valve with Bi-Level Vertical Float is a hydraulically operated, diaphragm actuated control valve that controls eservoir filling, opening at preset reservoir low level, and shutting at preset high level. During filling, it sustains minimum upstream pressure regardless of fluctuating flow or reservoir level.
