Abstract: Sealing adapters, pressure testing systems, pressure testing system kits, and associated methods. A sealing adapter comprises an adapter body and a mounting flange extending radially away from the adapter body. The adapter body includes a first end with a first sealing surface, a second end, and a fluid passageway. The mounting flange defines a plurality of stud receivers configured to receive mounting studs of a device under test (DUT). A pressure testing system may comprise a frame, a clamp structure with at least one sealing adapter, and a pressurizing assembly for delivering a pressurized fluid to the DUT. A method of pressure testing a DUT may comprise operatively coupling the DUT to the pressure testing system and delivering the pressurized fluid to the DUT.

Abstract: Valve seal assemblies, valve testing machines including the same, and associated methods. A valve seal assembly includes a seal plate structure and a force transfer member. The seal plate structure includes a base seal plate, and additionally may include an expansion adapter seal plate. The seal plate structure may include a socket receiver, and the force transfer member may include a socket head that is received within the socket receiver. The force transfer member may define a force transfer member fluid channel, and the base seal plate may define at least a portion of a seal plate fluid channel that is at aligned with the force transfer member fluid channel. A method of utilizing a valve testing machine includes configuring a seal plate structure for use to test a valve and forming a fluid-tight seal between the sealing flange and the valve seal surface.
