Piston Airless Valve Diagnosis

Diagnosing problems with airless piston pump pressure valves.

Here is a way to test your piston airless spray pump to ensure the inlet valve and outlet valves, including the relief valve are functioning correctly.

This test is much easier to do and see the results with a large longer stroking airless piston pump compared to a small short stroke fast cycling piston airless sprayer.

A small airless spray tip that slows the output of the airless piston pump will make this test easier to read.

Airless Sprayers

Airless sprayers are an excellent method of applying decorative and protective paints or coatings to almost any surface quickly. Airless spray paint units when correctly setup are also capable of providing extremely high quality painted finishes.

Almost any type of paint or coating can be applied using an airless spray unit. Thin products such as stains, timber preservatives, lacquers, polyurethanes and enamels can be applied using an airless sprayer provided the correct filtration, spray tip and pressure setting is used.
