Quick Closing Non-return Valve
Specialised valves for turbine applications
Quick closing non-return valves mainly used in the turbine extraction pipelines that supply steam to the primary-secondary heater, auxiliary turbines and other equipment. They prevent reversal of flow and provide shut off, thus limiting the damage to the source equipment in the event of a trip.
The main function is the quick shut Off of the bleeding steam pipes, in case of loss of turbine load, to prevent the dangerous water carryover from the preheater back to the turbine.
