ABSTRACT:
A valve housing is cooled to minimize any temperature gain by the fluid being controlled. The valve member is moved by an actuator toward and away from a seat to control flow through the housing. The valve member and its stem are made from a heat conductive material. The valve member and its stem are cooled by conduction when the valve member is in an open or closed position.
