This Pressure Regulator is a great way of ensuring you spray at the correct pressure output. The valve will fit most sprayers which have the standard 18mm threaded fitting, including Matabi, Berthoud & Cooper Peglar models.
The regulator can be adjusted to 3 different pressures. It can be used as a 1 - Bar or a 3 - Bar pressure regulator as normal or can be used in the Free-floming option without removal from the lance assembly.
The top is simply pushed down and twisted to remove the grey top and the internal colour indicator is reversed and then re-assembled to change from 1 or 3 bar operation.
To change from pressure regulator to Free-flowing, the bottom black part is simply screwed anti clockwise to allow Free-flow.
