Why can rotary control valves achieve a higher shut-off pressure differential than linear valves?

The answer lies in their unique design. Quarter-turn valves, such as ball and butterfly valves, typically provide greater shut-off capability due to their torque transmission efficiency and optimized sealing structures.

In high-pressure applications, understanding the relationship between valve design and shut-off performance is critical for selecting the right control valve and ensuring reliable operation.

Most butterfly valves fail at high temperatures — seals degrade, leakage increases, and shutdowns become inevitable.

In this video, we break down:
✅ Temperature limits of soft-seal, hard-seal, and triple-offset designs
✅ What it really takes to achieve zero leakage
✅ Common field failures and how to avoid them

👉 Watch before your next valve selection
