Details
A Selector Valve lets one compressor feed and balance more than one diffuser. It splits your air supply into multiple outlets and lets you open, close and throttle each one, so you can dial in even aeration across a larger pond or tune the flow to each diffuser.
Choose your configuration
- Available in 2-way, 3-way, 4-way and 6-way configurations
- 3/8 inch, 1/2 inch, and 1/2 inch to 3/8 inch port options
- Split one compressor across multiple diffusers
- Balance and fine-tune airflow to each line
Pick the number of ways and port size that match your setup. Contact our team if you would like help.

Why a selector valve
One tuned manifold beats an untuned split
Running more than one diffuser off a single compressor only works well if you can balance the airflow to each line. Here is how a selector valve compares to splitting air without control.
Without a selector valve
Split air with no control
- Airflow follows the path of least resistance, so one diffuser hogs the air
- No way to open, close or throttle an individual line
- Uneven aeration across a larger pond
- Adjustments mean disconnecting and re-plumbing
With a selector valve
Balance every line from one point
- Feeds and balances more than one diffuser from a single compressor
- Open, close and throttle each outlet independently
- Dial in even aeration across a larger pond
- Choose 2, 3, 4 or 6 outlets and the port size that matches your setup
What it does
Feed and balance multiple diffusers from one compressor
A selector valve splits your air supply into multiple outlets and lets you tune each one, so a single compressor can run a multi-diffuser layout with even, controllable airflow.
Split one air supply
Divide the output of a single compressor across multiple diffuser lines instead of running one diffuser at a time.
Throttle each outlet
Open, close and fine-tune the flow to each line so no single diffuser starves the others.
Even aeration over a larger pond
Balance airflow across your diffusers to keep aeration consistent from one end of a bigger pond to the other.
Match your configuration
Pick from 2, 3, 4 and 6-way bodies with 3/8", 1/2", and 1/2" to 3/8" port options to suit your tubing and diffuser count.
