• Split One Line Into Four
  
• Controllable At Each Valve
• All Metal Construction

A gang valve is a great way to split air between accessories or multiple aquariums. This gang valve features four outlets and up to two inlets. Each outlet has fine controls to adjust the amount of air per outlet. 

With two inlets, this allows you to feed two airlines in to combine their strength then split it up to 4 ways. Alternatively you can have one line coming in and connect the gang valve to another gang valve to split it eight ways allowing you to daisy chain them. 

Keep in mind that each time  you split the air, each outlet will have a weaker output. The more outlets you have, the more fine adjustments you'll need to make.
