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.
