How Special Valves Are Selected

Material selection depends on process conditions and operating environment:

Media corrosiveness and chemical composition
Chloride concentration and seawater exposure
Operating pressure and temperature
Abrasive or erosive flow conditions
Process compatibility and service life requirements
Pressure drop and shut-off performance

Proper material selection helps maintain structural integrity, corrosion resistance, and long-term sealing reliability.
