PowrLiner 2800 PRIME/SPRAY Valve Assembly (P/N 800-915)

Titan PowrLiner 2800 Prime Spray Valve Assembly – P/N 800-915

The Titan PowrLiner 2800 Prime Spray Valve Assembly (Part Number 800-915) is a control valve designed for use on the Titan PowrLiner 2800 line striping system. This component allows the operator to switch between prime and spray modes, directing material flow either back to the return line or through the spray hose and gun. This valve assembly is used directly on the fluid manifold area of the sprayer and plays a critical role in system startup, pressure release, and daily operation. Proper valve function helps ensure smooth priming, consistent spray output, and safe pressure control during shutdown.

Where It Is Used

The Prime Spray Valve Assembly is installed in the fluid control section of the Titan PowrLiner system. It manages coating flow during:

• Initial priming of the pump
• Switching from circulation mode to spray mode
• Pressure relief before servicing or cleaning
• Routine flushing and maintenance

Because the PowrLiner 2800 is commonly used as a pavement and athletic field striping unit, this valve is an important part of maintaining reliable performance in both road marking and turf applications.

Why This Valve Matters

On any Titan sprayer, the prime/spray valve is a high-use component. Frequent switching between modes during striping jobs can lead to wear over time. If the valve becomes difficult to turn, leaks material, or fails to fully divert flow, it may affect spray consistency and system pressure. Using the correct replacement parts ensures proper fitment and compatibility with factory specifications for the Titan paint sprayer. The 800-915 assembly is built to match the original configuration of the PowrLiner 2800 fluid system.

Designed for Line Striping Applications

The PowrLiner 2800 is widely used for parking lots, athletic fields, and light road marking projects. As part of the core Pavement Marking Sprayer Parts group, this valve assembly supports controlled paint delivery required for clean, accurate striping.

Contractors servicing athletic facilities also rely on dependable Field Marking Sprayer Parts to minimize downtime. Replacing worn valves promptly helps maintain steady pressure and predictable spray patterns during marking operations.
