Patent number: 10724642Abstract: A unitary valve trim assembly that can be easily installed in and removed from a valve body of a process control valve. The valve trim assembly includes a valve cage and a valve seat. The valve cage has a first projection that extends in a first direction that is perpendicular to a longitudinal axis of the valve cage. The valve seat has a second projection that extends in a second direction, opposite the first direction, that is perpendicular to the longitudinal axis.

Patent number: 10458555Abstract: A control valve includes a body having an inlet and an outlet and a valve seat positioned in a passageway between the inlet and the outlet. A valve plug is positioned within the body and is movable between an opened position and a closed position to modulate a fluid flow at the outlet. A cage is disposed within the body adjacent the valve seat and proximate the valve plug and has a circumferential wall having an outer surface and an inner surface aligned along a longitudinal axis of the cage. The outer surface of the cage defines an outer flow length and the inner surface defines an inner flow length that is less than the outer flow length.Type: GrantFiled: April 19, 2017Date of Patent: October 29, 2019Assignee: FISHER CONTROLS INTERNATIONAL LLCInventor: Michael W.
