The correct choise of shut-off valve depends on different factors: How big is the pipe dimension? What is pressure and temperature? What is the requirement for the leek? Is the media abrasive?

For more extreme tasks, such as overheated steam (over 12 bar), valve types like seat valves, piston valves and gate valves will be usable. Here you should be aware that only the piston valve can achieve 100% density.
DVC offer all of the valve types and many others - see them below.
Our shut-off valves are divided into the following categories:
