Abstract
A control disk for a fluid valve has a disk body having at least one through hole, the body having an upper surface for contacting another control element of the valve and an opposed lower surface. The upper surface is formed with a raised undulating contact surface. The raised undulating contact surface defines pockets suitable for receiving a lubricant.
