Clean Fluids, Normal Temperature and Pressure Conditions: Routine inspection every 3 to 6 months, including visual inspection for leaks, sealing performance, and operational flexibility.
Fluids Containing Particulate Impurities: Wear is accelerated; inspection every 1 to 3 months is recommended, focusing on valve core and seat wear, and thorough cleaning of the upstream filter.
High Temperature and High Pressure Conditions: Materials are prone to aging and deformation; maintenance every 2 to 4 months is recommended, including inspection of seals, bolt tightness, and actuator condition.
Corrosive Media (e.g., acids, alkalis): Corrosion rates are rapid; maintenance should be shortened to every 1 to 2 months, or even less, focusing on corrosion signs on the valve body and valve core, and the integrity of the anti-corrosion coating.
Frequent Operations (e.g., automated production lines): Comprehensive maintenance every 1 to 3 months, checking valve core, seals, actuator wear, and response accuracy.
