This simple non-electronic device is the key to reliable repeatable and safe operation. The PORV controls the foam concentrate flow path by diverting the excess foam concentrate, not utilized in the injection process, back to the foam concentrate tank. The PORV takes a water pressure signal from the main waterway and shifts the valve mechanically to control the system.
The control panel consists of a placard with operating instructions, low concentrate level warning light, on/off power switch and fully adjustable concentrate metering valve. This metering valve is infinitely adjustable from 0% to 1%.
