Zusammenfassung:	A seat plate which maintains constant contact and load against the gate to keep sealing surfaces protected is disclosed. The seat plate has a dynamic seat function ie live-loaded to follow the gate surface during stroking and high temperature changes. The valve maintains a positive barrier between body steam chamber and process fluid through port. The valve uses an extended seat plates to maintain constant contact with gate in all positions such that all process is captured and not allowed to enter body chamber. The seat plate allows for sufficient axial seat travel upstream and downstream to balance sealing load on both sides of gate. In addition, an axial hard stop on each seat allowing upstream seat to maintain sealing contact with gate.
