视频 In-Service Considerations for FE-Compliant Valves
Key guidance for ensuring the ongoing fugitive emissions–qualified performance of facility valve populations.
WKM 320 Series
Floating ball valves
Previously, manufacturers have had to use a vented ball configuration to avoid trapping cavity pressure, limiting the valve to work in only one direction.
The WKM 320 Series floating ball valve features a patent-pending seat that enables internal cavity relief while maintaining bidirectional sealing capability.
Advantages
- Bidirectional sealing capability
- Built-in cavity relief to prevent excess pressure buildup around the ball
- Lower break-to-open torque for reduced actuation requirement and easier operation
In every trim, WKM 320 Series valves include NACE compliance, fugitive-emissions capabilities, and fire-test certification to API Spec 607 7th Ed.
