The 546 PRO lever series focuses on the brand-specific implementation of functional product features. The distinctive shape of the lever references the responsibility of opening and closing the ball valve within piping systems. The faceted asymmetrical shape creates an optical presence clearly communicating the opened or closed position. With pins in the black inlay the lever can be used to open the ball valve for maintenance. By pressing down the locking ring, the lever position can be set and optionally secured with standard padlocks. The 546 PRO lever series includes different product sizes.
