DESCRIPTION
Cage Trim, Dual Inlet & Outlet for Through-Flow
The Mark 58FT/A features three ports: a bypass outlet on the bottom and two side ports which are directly connected to serve as dual inlet and outlet for through-flow. The Mark 58FT is designed to be installed in a “T” fashion such that the fluid normally flows in one side and out the other side; whereas the Mark 58A is designed to be installed with one side port as an inlet and the other side port plugged with the flow being relieved through the bottom bypass.
