Green-Handle Maxi Valve — Barbed Inline Shutoff

A green-handle maxi valve provides a manual shutoff between two irrigation tubing sections. The straight body has a barbed connection on each end, making it suitable for an inline control point in a matching tubing run. Select the 16, 20, 25 or 32 mm size to fit the line you are installing.

Control the line at a simple inline joint

The hand-operated green handle sits above the valve body, while the two barbed ends connect the line on either side. This arrangement adds a control point within the run without requiring a threaded adapter at that joint. Position the valve where the handle remains accessible after the tubing is laid out.

Choose the line size

• 16 mm connection option.
• 20 mm connection option.
• 25 mm connection option.
• 32 mm connection option.

Match the selected size to both tubing ends and verify the actual tubing fit before assembly. Pipe diameter labels can vary between systems, so check the tubing dimensions and construction as well as the stated nominal size. Choose the retaining method appropriate to the tubing and installation rather than assuming the barb alone suits every line.

Fit it without straining the tubing

Stop the supply and release the pressure before cutting the line. Make clean, square ends and seat the tubing fully over each barb. Align and support the run so it does not pull sideways on the valve. Leave space for the green handle to move. Restore water gradually and inspect both connections during the first irrigation cycle. Release trapped pressure before disconnecting the line for servicing.

Sold as one maxi valve in the selected size. Tubing and additional installation components are separate.
