Green-Handle Barb Takeoff Valve | 16, 20 & 25 mm

A green-handle barb takeoff valve provides manual control where an irrigation branch begins. Select the listed 16 mm, 20 mm or 25 mm option to suit the branch connection, then check the inlet arrangement against your supply line. The two sides serve different parts of the assembly and need individual fit checks.

Control a branch at its start

The green butterfly-style handle sits above a black body with a short takeoff end and a barbed lateral end. Keeping the control near the branch start makes it accessible when checking a row or changing downstream components. Leave enough space around the handle to operate it without pulling on the tubing.

Choose the connection size

Match the selected barbed end to the lateral tubing inside diameter. Confirm the supply opening and compatible sealing arrangement separately. The nominal branch size does not establish a universal hole size for a header. Supply material, wall thickness and the mating seal also affect fit. Check the complete inlet assembly before preparing any opening, especially when repeating the connection across several rows.

Install and inspect

Shut off the supply and release pressure before working. Clean the connection area, seat the compatible inlet assembly and push sound tubing fully onto the barb. Support the branch close to the valve so line movement does not load the supply joint.

Restore water gradually and inspect both connections. Operate the handle and confirm that branch flow responds as expected. Turn off the supply before adjusting a joint that seeps or moves. Check the assembly again during the first watering run.
