  • Patent number: 10041602
    Abstract: An axial flow regulator includes a lateral access port through a portion of the valve body that provides access to a valve seat assembly and/or other portions of the valve trim without having to remove or uncouple the outlet flange or the inlet flange from the adjacent pipe sections. The lateral access port may extend through an outlet flange portion of the valve body and is configured to allow a valve seat assembly to be laterally inserted into and removed from the outlet flange. A valve seat assembly which may be configured for installation in the axial flow regulator includes a pad holder and a support ring for the pad holder that is separable from the pad holder. The pad holder may have alignment struts projecting radially outwardly from a pad support body. The support ring may include strut receivers that slidably receive the alignment struts of the pad holder.

  • Patent number: 9091366
    Abstract: A control device includes a valve body, a seat ring, and an actuator. The valve body defines a flow-path for a fluid. The seat ring is disposed within the flow-path. The actuator is coupled to the valve body and includes a control member. The control member is adapted for displacement relative to the seat ring for regulating a flow of the fluid through the flow-path. The control member includes a sealing disk adapted to sealingly engage the seat ring and close the flow-path. The seat ring includes a plurality of orifices disposed within the flow-path such that the seat ring prevents at least a portion of the flow of the fluid from substantially perpendicularly impacting the sealing disk.
