Pneumatic Hand Valve Modifications for Steam Turbines

Elliott offers pneumatic nozzle ring overload hand valve modifications to improve the operational efficiency of your steam turbines. A pneumatic hand valve, which replaces the mechanical hand valve, allows the turbine governor to automatically open or close the hand valve to control steam flow when the load changes during operation.


This modification requires an electronic governor and is recommended for turbine generator sets or turbines that operate at variable conditions.
