Abstract:
A choke valve system includes a choke valve having a body and an annular seat disposed within the body. The choke valve also includes a plug configured to move relative to the annular seat between an open position in which a fluid is enabled to flow through the choke valve and a closed position in which the fluid is blocked from flowing through the choke valve and in which the plug contacts an annular seating surface of the annular seat. The choke valve further includes a damper coupled to the plug, and the damper is configured to absorb a load generated by contact between the plug and the annular seating surface of the annular seat as the plug moves into the closed position.
