The S3920 Butterfly Valve Lockout device is wedge-shaped and slides smoothly between the butterfly valve handle and the lever in an open, de-energized position. Feeding cable through an eyelet and around the valve neck helps keep the S3920 tight and the valve fully locked out. Applying a padlock – which takes only 30 seconds, start to finish – completes the task.
