Ball valves are probably the most used valves in the process industry. While ball valves do nothing more than start a flow or stop a flow, they have some advantages which make these valves very interesting for use in a process design.
A mechanical engineer who works with 3D solid modeling software usually needs a large amount of 3D CAD files to work out his design. Modeling these components is often a lot of work and therefore any component that can be downloaded from the Internet saves time and money. But what exactly is the value of a free 3D CAD model?
Most of our 3D CAD libraries contain 3D models in the step file format. It therefore seems a good idea to explain what the step file format is, and what the advantages and disadvantages of this file type are.
