BigBoy Differential Reservoir Valve
Applications:
Pump fed large storage tanks or reservoirs; it allows for a single level or variable minimum and maximum water levels
Mains/Gravity fed large storage tanks and/or reservoirs; it allows for a single level or variable minimum and maximum water levels
Rainwater Harvesting; as a backup water supply control valve, in the event of demand exceeding rainfall Operating Principle:
The BigBoy® will be closed when both weights are submerged (maximum water level). The valve will remain closed until the bottom weight is exposed (minimum water level). The valve will then open and remain open until the maximum level is reached. Benefits:
Enormous flow rate 1500 L/min at 1200 kPa
Soft closing, no water hammer
Longtail, no tank fittings
Adjustable water levels save electricity & increase pump life
Full on, full off
No float switches, no power required (pump requires pressure switch)
Less parts = less problems
