Titan 805-351A Inlet Valve
OEM Titan Fluid Section Component
Titan 805-351A Inlet Valve is a genuine OEM one-way check valve that controls material entry into the pump on compatible Titan airless sprayers, restoring reliable priming and consistent pressure when the original valve is worn, contaminated, or damaged.
Compatibility
Replace when the sprayer fails to prime, loses prime, develops unstable pressure, or shows visible wear on the valve ball or seat. This is a single inlet valve component, not a complete kit. Pusher assemblies and retaining clips are separate parts.

Titan 805-351A Inlet Valve for Airless Sprayer Priming and Pressure
Titan 805-351A is an OEM inlet valve component that controls one-way material flow into the pump on compatible Titan airless sprayers. It restores reliable priming and consistent pressure when the original valve is worn, contaminated, or damaged.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan inlet valve that controls the one-way flow of material into the pump on compatible sprayer units. |
| Function | Opens during the suction stroke to allow material into the pump chamber and closes during the pressure stroke to prevent backflow. Works with the outlet valve to create the pumping action. |
| Manual-Documented Application | Impact X 540I fluid section diagram lists 805-351A as item 19 (foot valve). |
| Optional Configuration Note | Impact 340 and Impact 400 cross-reference data identifies 805-351A as an optional inlet valve assembly. Not every machine of these models uses this component. Confirm the installed configuration before ordering. |
| Catalog-Listed Applications | Impact 440, 440X, 540, 640, 640 I/IA; Impact X 440; MultiFinish 440. Verify against the fluid-section diagram for your exact model. |
| Symptoms Addressed | Sprayer will not prime, intermittent pressure, reduced material output, contamination interfering with valve movement, and visible wear or deformation found during inspection. |
| Related Parts Commonly Serviced Together | 800-332 Viton O-Ring, 805-350 Pusher Assembly Clip, 805-216A Pusher Assembly, 805-234A Pusher Assembly, 762-145 Inlet Valve Ball, 762-058 Seat O-Ring. These are separate components and may not be included with 805-351A. |
| Distinction from Valve Kits | 805-351A is a single inlet valve component. It is not the same as the 805-846 Inlet Valve Kit or the 805-845 Outlet Valve Kit, which contain multiple service parts for their respective check-valve arrangements. |
| Target Users / Markets | Painting contractors, rental fleets, maintenance crews, and repair shops running compatible Titan Impact, Impact X, and MultiFinish airless sprayers. |
| OEM and Brand Information | Genuine Titan OEM component designed for correct fitment in compatible sprayer pump systems. |
| Commercial Benefits | Restores proper one-way flow control, ensures reliable pump priming, maintains consistent pressure, and extends pump service life. |
The 805-351A Inlet Valve is a targeted service component, not a complete fluid-section rebuild. Before ordering, confirm the valve arrangement in your machine's fluid-section diagram. When diagnosing priming or pressure problems, also inspect the inlet screen, suction hose connections, pump packings, and outlet valve, as these can produce similar symptoms.
