one kind of pressure Reducing Valve was produce for training purposes to help illustrate the main principles of how the valve works, Principal Design then animated the valve working with illustrated pressure within the cut away sections. From this model technical drawing were produced as well as a bill of materials and parts. In addition to the media work Principal Design also offered the facility to have the CAD model created turned into a physical model that the students would be able to interact with, and see the parts working and interaction with one another, dissemble and reassemble in a class room environment prior to working on the real valve in the field. With all CAD modeling at Principal Design we can pick up a project at any point in a project whether you
