Apex BigBoy Dual Level Automatic Float Valve – High Flow Tank Valve

The Apex BigBoy Dual Level Automatic Float Valve is an ultra-high flow mechanical valve designed to maintain minimum and maximum water levels in large storage tanks, reservoirs, and trough systems without the need for electricity. Using a differential dual-weight mechanism, the valve operates on a full on, full off principle, opening at the low water level and closing once the upper level is reached.

Built for demanding agricultural, commercial, and rainwater harvesting applications, the BigBoy valve delivers extremely high flow capacity, making it suitable for rapidly filling large tanks supplied by pumps, mains, or gravity systems. Its diaphragm-activated design ensures reliable operation while reducing pump cycling, energy consumption, and system wear.

The soft-closing action prevents water hammer and protects pipework and fittings from pressure shock. A long tail design allows installation in thin-walled tanks without additional fittings, while the self-cleaning mechanism minimises blockages and maintenance requirements. With adjustable level settings and robust construction, the BigBoy valve provides dependable, maintenance-free water level control in high-demand installations.
