Graco 15B874 Intake Valve – OEM Foot Valve Housing
The Graco 15B874 Intake Valve is a genuine OEM component designed for high‑pressure Graco airless sprayer pumps. This foot valve (intake valve) helps regulate fluid flow into the pump cylinder, ensuring reliable suction while maintaining a strict seal under demanding conditions. As part of the pump’s fluid section, it is crucial for priming, avoiding cavitation, and supporting consistent spray performance.

Features & Benefits
- Genuine Graco‑OEM part that ensures precise fit and reliable sealing performance.
- Constructed from high-quality materials that resist wear and corrosion in fluid‑handling environments.
- Maintains optimal pump priming and prevents backflow, improving efficiency.
- Critical for reliable suction from the fluid source and stable pump operation.
- Designed to withstand high-pressure cycles commonly found in professional coating systems.
Applications & Usage
The 15B874 Intake Valve is typically used in:
- Graco high‑pressure airless sprayer pumps.
- Fluid sections where reliable inlet check-valve performance is required.
- Maintenance or rebuild kits for spray systems to restore proper suction and pressure control.
- Professional finishing systems that demand consistent material flow during long or high-output jobs.
Frequently Asked Questions
It serves as a check valve to control fluid entering the pump while preventing reverse flow, ensuring stable and efficient suction.
Replace it whenever pump priming becomes difficult, fluid flow is inconsistent, or during a scheduled pump re‑build. A worn or damaged valve can lead to poor suction and performance issues.
While aftermarket valves may work, using the genuine Graco 15B874 ensures compatibility, proper material resistance, and reliable performance under high‑pressure cycles.
