Material: Use 304 SS for general use; switch to 316 SS for acids/chlorides. For food/pharma, choose low-carbon 304L/316L.

Type: Floating valves (e.g., Q41F) for low/medium pressure; fixed valves for high pressure.

Parameters: Match size (DN15–DN150), pressure, and flange standards. Ensure material temperature tolerance fits the medium.

Application: Use 316 SS in chemical/petroleum industries; 304 SS is cost-effective for water systems.
