High performance valves
Metso’s comprehensive valve offering provide for each type of steam turbine an ideal solution with butterfly valves for low pressure and intermediate pressure control and fast shut-off. Neles butterfly provide high capacity with less pressure loss. Jamesbury’s Wafer-Sphere valves provide a superior long term zero leakage.
All valves are capable for very fast stroking in case of trip situation.
Significant savings through high capacity
Our high performance butterfly valves with 2-shaft design and special disc shape offers an outstanding capacity, that provides a possibility to reduce pipeline diameter compared to single shaft designs. Full metal seat design provides low torque leading to a compact, light unit with small actuators compared to other seat types.
- High capacity leads either to higher efficiency of turbine or you may save costs due to smaller valve & pipe size and smaller actuator
- For a typical pneumatically operated low-pressure steam induction valve unit the saving of from a 20”unit to a 16” is up to 30%
