Frequently Asked Questions

Check the parts list for your exact model and revision (e.g., Ultra 1500 vs. Ultra Plus 1500). The list should reference 220629 (or 220-629) as the cylinder/inlet valve. If unsure, contact support with your model and serial number.

Difficult priming, pressure drop/flare, pulsation, or material flowing back into the inlet are common signs. If these occur on compatible machines, the 220629 Cylinder Valve may need replacement.

It’s best practice to inspect packings, seats, piston, and seals. If they show wear, replace them during the same service to restore full performance and reduce downtime.

Yes—this listing is for an OEM Graco cylinder valve. Some aftermarket options exist, but OEM ensures fit and performance on the listed models.

Depressurize and disconnect power first. Clean mating surfaces, check orientation, and torque per the service manual. After reassembly, prime with appropriate fluid and test for consistent pressure.
