System Installation

A typical installation of the BERMAD model 400Y-C-06 features remote actuation by way of the Relay Valve or
locally by the manual release override valve.

Pressure differential sensing points are led from the differential pilot to either side of the item to be monitored.

The BERMAD model 400Y-C-06 is ideally suited for foam concentrate proportioning (Fig. 1), regulating the
differential pressure between the foam and the water to ensure accurate foam to water ratio, regardless of
changes in the water flow or pressure.

The 400Y-C-06 is installed to prevent excessive flow, protecting the dosing pump from overflow damage often experienced during pump start up and during initial system pipe filling.

By sensing the differential pressure across the pump the 400Y-C-06 will modulate, preventing the flow from exceeding the recommended maximum.

When the differential pressure is lower than the pre-set maximum the 400Y-C-06 fully opens. The exceptional flow efficiency of the 400Y-C-06 ensures a reliable and fully functioning system performance.
