For ultimate flow control in a fish room, we use the an Air Control Valve near the aquariums for fine tuning eliminating the need to get up on a ladder when using these metal valves in a fish room air manifold loop.
These valves are excellent for central air systems.They are easily tapped into regular PVC pipe to provide outlets for all your tanks. These will self tap into the pvc once you drill a small hole.
- Threaded Metal Valve
- Precise Air control

These valves are meant to be screwed into pvc. Often used with a Linear Air Piston Pump to run an air loop around a room filled with aquariums. Build your own custom gang valve using these. These last a lifetime and are used by most fish stores and fish breeding facilities.
