Zusammenfassung:A steam valve (10) includes a housing (12) defining a steam inlet (14) and a steam outlet (16) in fluid communication with a valve cavity, and an annular valve seat disposed within the valve cavity. A control valve (17) is configured to selectively engage the valve seat (21). The steam valve (10) further includes a stop valve (19) configured to selectively engage the valve seat (21). The steam valve (10) includes a pressure seal head (100) configured to receive the stop valve (19). The pressure seal head (100) includes an elongated body (102) having a bore (106) extending longitudinally through the elongated body (102); and a nose piece (104) extending from an end of the elongated body (102). The nose piece (104) has at least a tapered end portion (122) and a bore (128) extending longitudinally therethrough.
