  • Seal arrangement for a piston valve
    Patent number: 7384022
    Abstract: A sliding seal arrangement in particular for a valve having an anodised aluminium coating in contact with the seal. The coating is produced so that inclusions in the surface of the coating are substantially aligned. The direction of motion of the sliding seal in use is then substantially aligned with the direction of the inclusions resulting in greatly reduced wear on the seal.
