Pain Points and Proposal

1. Jamming, Internal Leakage, Short Service Life:

1.1 Seat coating corrosion/spalling  

1.2 Seat sealing surface scratches  

1.3 Spring corrosion failure  

1.4 Solid buildup on ball  

2. External Leakage:

1.1 Body flow path erosion  

1.2 Body corrosion

1. Sticking, internal leakage, short service life: Value presentation video of corrosion-resistant coating.
2. External leakage solution: Valve body flow path liner, with the liner surface treated using anti-galling coating technology.
