Yes—this kit includes the outlet valve assembly and associated small parts required for the service. Exact contents may vary by kit revision; if you need a contents breakdown, let us know your sprayer’s model/series.
Depressurize and unplug the sprayer, follow the service procedure in your model’s manual, keep the valve seat and bore clean, torque to spec, and test with water before paint. Replace worn inlet components at the same time if needed for a complete refresh.
