  • Steam conditioning butterfly valve
    Patent number: 5439619
    Abstract: The present invention is a steam conditioning valve for use in simultaneously reducing temperature and pressure in a superheated steam line. The invention provides a butterfly-type valve with desuperheating water nozzles oriented on its downstream face. In the preferred embodiment illustrated, valving is included to control the flow of water to each of the nozzles selectively. The present invention provides an improved steam conditioning valve which is both simpler and more economic than existing steam conditioning valves or the combination of pressure reducing valves and desuperheaters.
