FEATURES and BENEFITS
- Forgiveness - Our ring set with patented cup and cone design, delivers higher precision fit to optimize field performance.
- Cost effectiveness - The EVSP design permits a controlled radial expansion to create an effective seal against both valve stem and bore. This engineered set can be used to seal older more worn valves. Emission compliance can be achieved without necessarily replacing valves or the maintenance expense of bringing the valves back to manufacturer’s specifications.
- Safety - This Style is fire safety tested and chemical resistant. It is well recognized in hydrocarbon and chemical processing industries as a reliable and ideally suited solution for low emission valve stem sealing.
