The 1/4" Micro Flow Valve (Barbed) gives you the power to adjust or completely shut off water flow to individual plants or garden rows. While your main timer controls the schedule for the entire zone, this manual valve allows for "micro-management" of specific areas that may need less water or are temporarily empty.
These compact irrigation fittings install directly inline with your 1/4" micro tubing. With a simple twist of the colored knob, you can throttle the flow down for delicate seedlings or open it up for thirsty shrubs. They are the perfect upgrade from standard transfer barbs when you need variable control.

Add control to your line in seconds:
Step 1: Cut the Tubing
Locate the section of 1/4" micro tubing where you want to add control (usually near the plant or at the start of a pot cluster). Cut the tubing cleanly.
Step 2: Insert the Valve
Push the cut ends of the tubing onto the barbs on either side of the valve. The valve is bi-directional, so flow can go either way.
Step 3: Adjust Flow
Turn the handle to open, close, or throttle the water flow to your desired level.
Note:
This valve is for 1/4" tubing only. To control flow on a 1/2" mainline, use a larger 1/2" valve.
