    摘要： A seat assembly for a choke valve assembly includes a housing having an internal passage, in which the housing is formed from a non-superhard material. The seat assembly also includes a seat disposed within the internal passage of the housing. The seat is configured to engage a needle of the choke valve assembly while the choke valve assembly is in a closed state, and the seat is formed from a first superhard material. In addition, the seat assembly includes an annular insert disposed within the internal passage of the housing downstream from the seat. The annular insert is formed from a second superhard material, and a maximum cross-sectional area of the seat along a longitudinal axis of the seat assembly is greater than a maximum cross-sectional area of the annular insert along the longitudinal axis.

    摘要： A movable valve element (24) is comprised of a valve member (22) and a leaf spring (26). A passage forming member (12) is securely fixed to a valve chamber forming member (10) that forms a valve chamber (S). The passage forming member (12) has a fluid passage (14) extending from one end to the other end thereof, with the one end (14a) of the fluid passage (14) constituting an outlet port of the valve chamber (S). The passage forming member (12) has an O-ring (20) surrounding and spaced apart from the outlet port (14a), the O-ring (20) constituting a valve seat. Spring force of the leaf spring (26) brings the valve member (22) into pressure contact with the O-ring (20), to form a closed valve state.
