Graco HVLP Check Valve Kit Complete

The Graco 256957 HVLP Check Valve Kit is a vital maintenance accessory designed to regulate air pressure delivery inside your turbine spray configuration. This inline, one-way directional valve acts as a critical gateway—allowing specialized atomizing air to flow seamlessly from the gun body into the material cup to pressurize the coating, while physically preventing paint or air from rushing backward into the gun's primary air channels.

Because they continuously manage pressurized paint environments, check valves will naturally clog or fail over time due to material residue. Keeping a spare kit in your storage box is the single best way to avoid severe project downtime and keep your fine-finishing operations running without interruption.

Diagnostic Pro-Tip: Is your HVLP gun continuously spitting or shooting a stream of paint out of the nozzle after you have completely released the trigger? This is the classic symptom of a blown or clogged check valve. Swapping it out with this genuine kit instantly remedies the problem.
