Seal seat for high pressure pumps and vessels

摘要

A seal assembly for a high pressure vessel. The pressure vessel can include a first material and can have a face with a bore extending through the face such that the bore has an edge at an intersection of the bore and the face. A check valve, including a second material, can extend into the bore and a seal seat, including a third material different than at least one of the first and second materials, can be positioned between the pressure vessel and the check valve body to reduce galling and/or fretting of the pressure vessel and check valve body.
