2393043 Inlet Valve is a genuine OEM replacement component for Titan PowrLiner airless line stripers. The inlet valve controls the flow of coating material into the pump cylinder during the upstroke and seals to prevent backflow on the downstroke. A worn or contaminated inlet valve can cause loss of prime, pressure fluctuations, and reduced spray efficiency. Replacing the valve restores proper pump function and consistent line‑stripping performance.

The Titan 2393043 Inlet Valve is a critical component of the pump fluid section. It opens during the piston upstroke to draw coating material into the cylinder and closes on the downstroke to direct pressurized material toward the outlet valve. A properly sealing inlet valve is essential for maintaining prime and delivering consistent line‑stripping pressure.
Abrasive materials, dried coating, or normal wear can cause the inlet valve to leak or stick. Symptoms include difficulty priming, pressure surging, reduced output, or material draining back into the container. Replacing the inlet valve with an OEM component restores pump efficiency and ensures reliable striping performance.
| Draws material | Opens during upstroke to allow coating into the cylinder |
|---|---|
| Seals on downstroke | Closes to prevent backflow and direct pressure to outlet |
| Maintains prime | Holds fluid in the pump when the sprayer is off |
| Loss of prime | Sprayer won't prime or loses prime quickly |
|---|---|
| Pressure surging | Fluctuating pressure during operation |
| Material backflow | Coating drains back into the container when suction tube is removed |
| Visible wear / debris | Damaged seat, worn ball, or contamination inside valve |
Part 2393043 is the OEM inlet valve for the following Titan PowrLiner line striping models. Always verify with your machine's parts diagram.
| Brand / Model | Component |
|---|---|
| PowrLiner 3500 72v | Inlet Valve |
| PowrLiner 3000 | Inlet Valve |
| PowrLiner 3500s | Inlet Valve |
| PowrLiner Elite 3500 | Inlet Valve |
When replacing the inlet valve, inspect or replace these components to ensure complete pump restoration.
The outlet valve seals the pressure side; often fails simultaneously with the inlet valve.
Worn packings can cause similar symptoms; inspect for leaks around the cylinder.
A clogged strainer or leaking suction line can mimic inlet valve failure.
