| System / Model Type | Description |
|---|---|
| Graco Metering Valves & Fluid Control Modules | Valve assemblies requiring seating surfaces for fluid control |
| Graco Pump and Dispense Systems | High‑pressure units with internal valve seats subject to wear and replacement |
| Graco Repair Kits & Service Modules | Service part for valve seat replacement in Graco valve repair kits |
The Graco 15A830 Valve Seat is a precision‑machined internal component designed to serve as the primary sealing surface in Graco valve and fluid‑metering assemblies. This valve seat provides a critical interface where the valve or plunger meets the seat surface to properly control fluid flow and prevent leak‑back.
Manufactured to tight tolerances, the 15A830 ensures reliable sealing under high pressures and frequent cycle counts. As valves wear, the seat surface can degrade, leading to inefficiencies and leakage. Replacing the valve seat with this service part restores proper performance and longevity of the valve module.
