FOAMAX PRV Pressure Reducer (FDV)

The pressure reduction system is based on Raphael's FDV-Ra valves, equipped with a pilot for precise pressure reduction at variable flows. Installed FDV-Ra valves have a range of optional materials and coatings to suit operating conditions; the basic principle of the system remains the same.

Under flow conditions, the pressure-reducing pilot senses the downstream pressure and maintains it at a constant level through real-time control.

The system is equipped with a self-cleaning filter, can be installed in any orientation, and is suitable for all fire water supply systems.
