Blue-Handle Barb Takeoff Valve for Drip Irrigation

A blue-handle barb takeoff valve gives manual control at the start of an irrigation branch. Use the handle to open or close the branch flow, and select the listed 16 mm or 20 mm option to suit the lateral connection.

Control an individual branch

The blue butterfly-style handle sits above the black valve body, where it is easy to reach during line checks. Closing the valve lets you shut off that branch while attending to the downstream line. Shut off and depressurize the supply before removing the valve or working on its inlet connection.

Match the connection before installation

• Available selections: 16 mm or 20 mm.
• Control: manually operated blue handle.
• Connection role: takeoff inlet with a barbed lateral connection.

Check the branch tubing inside diameter against the chosen barb. The nominal branch size does not establish the inlet hole diameter or seal size. Confirm the supply-side connection, pipe wall and sealing arrangement independently before preparing the header.

Fit and inspect the assembly

Work with the supply off. Clean the connection area, use the compatible inlet seal and seat the lateral tubing fully onto the barb. Leave enough room to move the handle without interference from nearby pipes or supports. Avoid using the handle to force the connector into position.

Flush debris from the line before normal use. Restore water gradually, operate the handle and check the inlet and outlet for seepage. Keep the lateral supported so its movement does not pull on the valve.

Choose by connection as well as color

Blue identifies this handle version; connection dimensions determine fit. For another line layout, compare the connection types in irrigation valves before ordering the parts for your system.
