Gang Valve – 4-Way

The 4-way gang valve is the central hub for any multi-tank or multi-device air distribution system. By connecting one air pump to four independently controlled outlets, the keeper can run four air stones, sponge filters, or other devices at precisely calibrated individual flow rates from a single pump.

This approach is particularly common in breeding rooms, fishrooms, and quarantine setups where multiple small tanks run simultaneously. The individual slider valves allow the flow to each tank to be fine-tuned or shut off entirely without affecting the remaining outlets.

For the valve to function properly, the air pump must be rated to supply all four outlets simultaneously — check the pump's maximum airflow specification before purchasing.
