Manual Dual-Tank Selector Valve
A FoamPro manual dual-tank selector valve shall be installed. The valve shall be designed for rapid changeover of two (2) foam concentrate reservoirs, using a lever located on the pump operator's panel. The dual-tank valve shall provide a clean water flush of the foam concentrate pump. The system shall automatically read the low-tank sensor for whichever foam tank is in use. The valve shall be capable of operating pressures up to 500 psi (34.5 bar) and shall meet NFPA requirements. The digital display shall show performance information for each type of foam concentrate.
The unit shall be complete with the following components:
1. An electronic circuit
2. Switches with indicator lights and nameplate
3. Controller interface cable
4. Three (3) 3/4" check valves
5. Two (2) 3/4" line strainers
Full flow check valves shall be provided to prevent foam contamination of the fire pump and water tank or water contamination of the foam tank.
