Valves - Specific Services
In case of a specific service - the choose of a valve may be simplified by following an established practice.
| Services | Main | Secondary |
|---|---|---|
| Gases | Butterfly valves Check valves Diaphragm valves Lubricated plug valves Screw down stop valves |
Pressure control valves Pressure relief valves Pressure reducing valves Safety valves Relief valves |
| Liquids - clear up to sludges and sewage | Butterfly valves Screw down stop valves Gate valves Lubricated plug valves Diaphragm valves Pinch valves |
|
| Slurries and liquids with solids | Butterfly valves Pinch valves Gate valves Screw down stop valves Lubricated plug valves |
|
| Steam | Butterfly valves Gate valves Screw down stop valves Turbine valves |
Check valves Pressure control valves Pre superheated valves Safety and relief valves |
- Slurry - a thin mixture of a liquid like water and finely divided substances, such as cement or clay particles
- Sludge - a semi-solid slurry. Wastewater solids are also referred to as sludge.
