Here at Holland Supply, we take special care to ensure our customers know everything they need to know to properly use their equipment. We do this so that not only do they get the best use out of their equipment, but to also keep their customers, employees, and infrastructure safe. Whenever the need arises, we're always able to answer any questions or provide guidance when customers ask for it. But our team also loves to host training opportunities to help further customers' education about the products we have to offer.


The Holland team has held several hands-on training sessions centered on the Model 441 and Model 461 regulators. In the guide that you can download on this page, we've compiled all of the valve assembly parts numbers you would need for the Model 441 and Model 461 regulators from Utility Solutions Group. We wanted to share our knowledge to make it easy for you to find exactly what you need whenever a part needs to be replaced on your regulator.
