RATIO CONTROLLER

UL Listed wafer-style ratio controller designed for accurate foam concentrate proportioning across a wide range of flow rates and pressures. Operating on the venturi principle, the Ratio Controller introduces foam concentrate into the water stream by creating a low-pressure zone at the inlet nozzle, automatically adjusting concentrate flow as system demand varies.

Compatible with Bladder Tank Proportioning Systems, Inline Balance Proportioning Systems, and Skid Mounted Pump Balance Proportioning Systems, the FGRC series offers a reliable and passive proportioning solution with no moving parts requiring external power.
