Features and Benefits
- Superior leakage resistance results from the shutoff design and construction that reliably complies with FCI 70-2 Class V for control valve applications and API 598 for On-Off applications.
- Constant temperatures within the valve stem and packing region are ensured with a comprehensive solution for packing/heat tracing including integrated heating, controls, and sensors
- Reliable packing performance owing to materials and configuration engineered to match the customer’s specific packing load and performance requirements
- Minimized maintenance can be achieved with in-line maintenance (consult Flowserve engineering special
