Titan 700-258 PrimeSpray Valve Assembly
OEM Titan Fluid Section Component
Titan 700-258 PrimeSpray Valve Assembly is a genuine OEM bypass valve that switches the fluid section between prime and spray modes on compatible Titan airless sprayers, eliminating air and delivering consistent material flow.
Compatibility
Replace if the sprayer fails to prime, remains in bypass during spray mode, loses pressure, leaks from the valve handle, or the handle is stiff or seized.

Titan 700-258 PrimeSpray Valve Assembly for Airless Sprayer Mode Switching
Titan 700-258 is a genuine OEM prime/spray bypass valve assembly engineered to control fluid routing in the pump manifold of compatible Titan airless sprayers. In PRIME mode, the valve directs material back to the supply container to purge air and fill the fluid section. In SPRAY mode, it closes the recirculation path and routes high-pressure material to the gun.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | Genuine Titan OEM prime/spray bypass valve assembly for compatible airless sprayers. Switches the fluid section between prime (recirculation) and spray (high-pressure) modes. Documented in official Titan service manuals including the Impact 540. |
| Function | In PRIME mode, directs material from the pump outlet back to the supply container to purge air and fill the fluid section. In SPRAY mode, closes the recirculation path and forces material through the high-pressure hose and gun. Also acts as a pressure relief valve when partially opened. |
| Compatible Titan Machines | Titan 330, 440i/IX, 540, 640i/IX, and 740i/IX Airless Sprayers. Also compatible with Impact, Epic, PowrLiner, and RentSpray models. Always confirm fitment using your exact model's parts diagram and serial number. |
| OEM Part Number | 700-258 PrimeSpray Valve Assembly. Replaces Wagner 0507690. |
| Replacement Indicators | Difficulty priming or failure to build pressure; material leaks from valve handle or housing in spray mode; pressure surging or inconsistent spray pattern; sprayer remains in bypass during spray mode; stiff or seized valve handle. |
| Related Parts Commonly Serviced Together | Valve handle (700-697), valve stem O-ring (700-721), gasket, cam base, groove pin, manifold filter (730-067), outlet fitting (227-006). |
| Common Problems Solved | Restores proper priming and mode switching, eliminates pressure loss from internal bypass, stops leaks from the valve, and ensures reliable material delivery for consistent spray performance. |
| Why Genuine OEM | Exact dimensions, seal materials, and flow characteristics ensure proper fit and reliable mode switching under high pressure. A low quality or incorrect valve may leak internally, fail to seal, or seize, compromising sprayer performance and safety. |
Service guidance: When replacing the 700-258 valve, follow the procedure in your sprayer's service manual. Push the groove pin out of the valve handle, remove the handle and cam base, loosen the valve housing with a wrench, and thread the new housing into the pump block with the gasket in place. Lubricate the cam base with grease and align it with the pump block before reinstalling the handle and pin. Always relieve system pressure before servicing.
