The special ball seating geometry ensures that material stuck to the ball is removed during each switching action. This guarantees permanent simple switching even for adhesive goods. The wear resistance achieved from boronizing the ball and the ball seat provides for a long tool life even with highly abrasive media. Additional armouring of the fitting can be provided upon request.
