Cla-Val products are built to last a lifetime and we stand by our products.  We have one of the best warranties in the business and our valves are designed for trouble-free operation, especially if periodic maintenance is performed per the products' Quick Manual and IOMs. You can find the manuals on the individual product pages throughout this webiste.  A quick way to locate the manuals is to enter the basic model number (such as 90-01 or 50-01) in the "Search" field at the top right corner above.  See below for an example. 

Should repairs become necessary, we invite you to click on "Field Service"  to locate a service provider near you. If you require assistance in locating the information you are looking for, please email us at
