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
* 32, 40 and 50mm sizes

Specifications:

* Working pressure 15 kPa - 1200 kPa
* Temperature range 1 - 60°C
