Master Lock®Company LLC’s latest entry into the Safety Lockout/Tagout (LOTO) arena, the new S3920 Butterfly Valve Lockout, turns the tables on devices that merely clamp down on the valve handle to keep it disengaged.
The Master Lock wedge-shaped device slides smoothly between the butterfly valve handle and the lever in an open, de-energized position, and easily adjusts to fit virtually any size butterfly valve. Feeding cable through an eyelet and around the valve neck keeps the S3920 tight and the valve fully locked out. Applying a padlock completes the task, and it takes only 30 seconds, start-to-finish; see demonstration video at http://bit.ly/1bfukit.
