WKM 320 Series

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.
