Part number 0270951 is a prime/spray valve kit that directs fluid flow for priming or spraying operations in compatible sprayer systems. This kit includes the valve assembly and necessary components to switch between recirculation and spray modes. It is compatible with HVLP Airspray ProFinish AS1130; SprayTech AirCoat; SprayTech ED655; and SprayTech ED1075 models. Replacing a worn or leaking prime/spray valve kit restores proper flow control and prevents material waste.

The 0270951 prime/spray valve kit is a complete replacement assembly that controls the direction of fluid flow within compatible sprayer systems. It is specifically designed for use with HVLP Airspray ProFinish AS1130; SprayTech AirCoat; SprayTech ED655; and SprayTech ED1075 models. This valve allows the operator to select between two modes: prime mode, which recirculates fluid back to the container for mixing or purging air, and spray mode, which directs fluid to the gun for application. The kit typically includes the valve body, internal seals, handle or actuator, and any necessary mounting hardware. Proper operation of this valve is essential for efficient priming and consistent spraying. Over time, the valve can wear due to abrasion from paint particles, chemical attack, or seal degradation. A faulty valve may leak, fail to fully switch modes, or allow fluid to bypass. Symptoms include difficulty priming, material leaking from the valve body, or inability to build pressure. Replacing a worn prime/spray valve with this genuine kit restores positive flow control and reliable operation. This ensures that the sprayer can be properly primed and that material is delivered to the gun only when desired. Regular inspection and replacement of this valve is recommended for maintaining optimal performance.
