**API 607 vs API 608: Key Differences and Applications**
When selecting ball valves for industrial applications, understanding API 607 vs API 608 standards is crucial. These specifications govern fire-safe testing and design, ensuring safety and compliance in critical environments.
**Core Specifications and Testing**
API 607 focuses on quarter-turn valves and defines fire-test requirements for soft-seated designs. API 608, however, covers metal-seated ball valves and includes broader design criteria. Both ensure integrity under extreme conditions.
**Functional Applications**
Use API 607 valves in systems requiring frequent operation and tight shut-off with resilience. API 608 valves suit high-pressure or corrosive services where metal seating is preferred for durability.
**Common Questions Answered**
Which standard is stricter? API 608 includes additional design mandates beyond fire testing. Can they be used interchangeably? Not always—consult specifications for compatibility.
