For example, you can use the ball valves, butterfly valves and the plug valves in most basic medium conditions. knife gate valves can be used in conditions when you have to immediately start and stop the flow of the medium while the filter valves can be used for liquids that have solids. One thing that you have to note with liquids is whether they will remain in their liquid form only. Some liquids can heat up and vaporize during the flow as well.
Temperature and pressure
The second thing that you have to consider before buying a valve is the pressure that the valve will have to handle. Temperature is equally important in this regard.

However, in general, PVC plastic, iron, carbon steel etc. are some great choices.
