The BERMAD Model FP 400E–5D is suitable for systems that include wet pilot lines with closed fusible plugs. Providing boosted local opening, it is recommended for systems with elevated fusible plugs. The valve is closed as long as the wet pilot line is pressurized. It opens in response to a hydraulic pressure drop in the wet pilot line.
