Flow media refers to the component that passes through the valve. Similarly, the type of fluid or gas plays a role in choosing the right kind of valve. In relation to this, it can produce reactions when in contact with the valve.
These valves are just part of the equation. Considerations should include the requirements of the entire system. For instance, the purpose of the piping system is relative to the suitability of the valve.
Valves should meet the criteria provided by the industry. Studies back up the standards followed by industries. By knowing what the industry requires and following this ensures minimal errors, accidents, and the likes.

Valves using soft seats often have limited pressure threshold. However, softer materials are great sealers.
These valve seats often use a type of polytetrafluoroethylene (PTFE) as a rule of thumb. One example is Teflon. One catch here, though, low-pressure applications should only use virgin PTFE.
Another soft material often used in ball valves is neoprene or fluorocarbon elastomer. Generally ideal for pulp and paper applications, this material is highly resistant to oil and moderate chemicals. However, this material is not great for highly corrosive acids such as hydraulic fluids.
Mid-range pressure applications use filled PTFE. On the contrary, high-pressure applications utilize polyether ether ketone (PEEK). Pure liquid or gas media applications use soft seats while abrasive medium uses metal seat ball valves. Meanwhile, low-pressure systems employ tungsten carbide as the coating.
Soft seat materials do not react well in high temperatures. Therefore, use a seat made from graphite. What determines the type of seating to use are the ball valve pressure rating and the materials.
