The right valve selection
State-of-the-art industrial plants often place high demands on the valves used; for example, in many processes the products are subject to extremely high temperatures, high pressures or aggressive media. In view of these facts, the selection of the right valve is crucial for the optimal safeguarding of the plant. With our product search, you will be able to find suitable valve solutions.
ADAMS offers different valves categories including reliable valves with various features and additional options for critical applications.Â
Ideal solutions
We continually develop tailor-made designs for our customers. In many cases they consist of minor changes to details of valves, but sometimes designs also need to be developed from scratch.
However, all of our solutions have one thing in common: our customers can be absolutely sure that the finished products are ideally suited to their requirements. Thus the application and product overview on the left simply serves as a guide for possible uses. We will be happy to discuss solutions for further ranges of application individually with you.
