Apex Big Boy Reservoir Valve 32mm / 40mm / 50mm

• Extremely high volume water inlet control device
• Soft closing, no water hammer
• Enormous flow rate 1500 L/min at 1200 kPa
• Full on, full off

APPLICATION
• Pump fed large reservoirs – it allows for a single level or
variable minimum and maximum levels within a reservoir/tank.
• Mains/Gravity fed large storage tanks and/or reservoirs
– it allows for a single level or variable minimum and maximum
water levels within a reservoir/tank.
• Rainwater Harvesting – as a backup water supply control valve,
providing a backup supply of water in the event of demand
exceeding rainfall.

HOW IT WORKS
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.

FEATURES & BENEFITS
• Enormous flow rate up to 1500 L/min (330 gal/min)
• Soft closing – no water hammer
• Adjustable water levels saves electricity & increases pump life
• Full on, full off – diaphragm activated
• No float switches – no power required (pump requires pressure
or flow switch)
• Long tail removes need for tank fittings on thin walled tanks
• Fully serviceable
• Can be used as a top up rainwater harvesting valve
• Patented self-cleaning mechanism minimizes
blockages
