BigBoy / BigAL
- Pump fed large storage tanks and/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.
- Rain Harvesting - as a back up water supply control valve, in the event of demand exceeding rainfall.
Features & Benefits

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 water level is reached.
Working Pressure: 15 kPa - 1200 kPa (2 psi - 175 psi)
Flow Rates: Very high, 1500 L/min at 1200 kPa. Fills a 30,000 litre tank in 30 min (600 kPa inlet pressure)!
Temperature Range: 1 - 60°C Tank valves must be insulated to protect the valve where the temperature can get below 1°C (minimum service temperature).
