PRODUCT INFORMATION
Bermad WW757-66-U – Level and Flow Control Valve with Bi-Level Vertical Float
The Model 757-66-U Level and Flow Control Valve with Bi-Level Vertical Float is a hydraulically operated, diaphragm actuated control valve that controls reservoir filling. The valve hydraulically opens at pre-set low level and shuts off at pre-set high level. During filling, it limits the flow to preset maximum, regardless of fluctuating upstream pressure or reservoir level.
Model 757-66-U is the first valve of its design in Australia to be compliant and certified for inclusion in municipal water supply and building services.
