PILOT OPERATED RELIEF VALVE
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.
CONTROL PANEL
The control panel consists of a placard with operating instructions, low concentrate level warning light, on/off power switch, and a fully adjustable concentrate metering valve. This metering valve is infinitely adjustable from 0% to 1%.
SAFETY INTERLOCKS
The system shall have a water pressure switch that prevents the unit from operating in the absence of water pressure. The system shall be provided with a foam concentrate low-level float switch. The float switch will turn off the system when the foam concentrate level is low. The system shall be provided with a momentary interlock override switch.
