The SPRAYTECH 555850 is a prime/spray valve assembly designed for use with Spraytech airless paint sprayers. This assembly controls the transition between priming and spraying modes, allowing the operator to purge air from the fluid path before beginning a spray application. It is a direct service component installed by painting contractors, maintenance technicians, and equipment repair professionals who need to restore proper fluid control function to a sprayer. The 555850 is an OEM-specified replacement part built to fit Spraytech equipment.
This valve assembly is suited for use in airless sprayer service and repair applications. It is typically installed when the existing prime/spray valve fails to shift correctly, leaks, or causes loss of pressure during operation. Installation is common in both professional painting service environments and equipment repair shops handling Spraytech brand sprayers.
Designed as an OEM-style replacement valve assembly for compatible Spraytech airless paint sprayers. Confirm fit against your specific model number before installation.
Installation should be performed by a qualified technician familiar with airless sprayer fluid system components. Before servicing, relieve all system pressure and disconnect the sprayer from its power source following the equipment manufacturer's depressurization procedure. Standard hand tools are typically required for valve assembly replacement. Refer to the Spraytech service documentation for your specific sprayer model to confirm proper assembly orientation and reassembly steps.
