Quick Closing Non Return Valve
Quick closing non-return valves are installed on the turbine extraction pipelines that supply steam to the primary-secondary heater, auxiliary turbines and other equipment. They prevent reversal of flow and provide a quick positive shut off, thus limiting damage to the source equipment in the event of a trip.
