20 mm Blue-Handle Start Valve for Drip Irrigation

This 20 mm blue-handle start valve places manual water control at the beginning of a compatible irrigation line. Its compact black body carries a blue wing handle, a blue locking nut on one side and a black start connection on the other. Use it when planning a line takeoff that needs an accessible shutoff point.

Check the start connection before ordering

The offered size is 20 mm. Check the actual line dimensions and the supply connection before choosing this valve. The black start end has a different structure from the blue line connection, so both sides need to suit the installation. Confirm any required hole, seal or mating fitting as a complete connection arrangement rather than selecting by line diameter alone.

Place control where you can reach it

The blue handle is positioned above the valve body. Leave enough space around it to operate the valve after the line is laid out. A start valve can help you isolate a selected watering run while checking a joint, changing a layout or disconnecting the downstream line after the supply has been shut off. Plan the position so that nearby pipes and fittings do not obstruct the handle.

Prepare the line and inspect the joints

Turn off the water supply and release pressure before fitting the valve. Prepare the line end cleanly and follow the connection procedure suited to the actual tubing and start fitting. Support the adjoining pipework so that the valve does not carry the weight of an unsupported run. Tighten locking components carefully and avoid forcing the plastic body.

Restore water gradually, inspect both sides for leaks and check that the handle remains easy to reach. Recheck the connection after the first watering cycle. Supplied as one valve; irrigation line and installation accessories are separate.
