How to Adjust Irritrol Spray Heads(VAN)

The Irritrol Pro-Van (variable arc nozzle) allows for a spray pattern from 0° to 360° to cover different shaped areas.

The Pro-Van adjustment is done without tools and can be done wet or dry. Adjustments are made by turning the adjustment ring.

Turn the adjustment ring clockwise until it stops. This will turn off all flow from the head and the arrow on top will now give you your right side alignment. Turn the sprinkler body until the arrow is pointing at the right edge of your desired spray pattern.

Turn the zone on, grab the adjustment ring and turn counter-clockwise until you have the pattern you need. If you need to reduce coverage slightly you can tighten the screw on top. This will reduce distance up to 25%. This is not generally recommended but is sometimes necessary.
