  • Pull handle butterfly valve lockout device
    Patent number: 11493147
    Abstract: A valve handle lockout device is configured to temporarily lock out a pull handle butterfly valve. The device includes an enclosure body, at least one lock hole, and a blocking wall. The enclosure body includes first and second enclosure portions having an opening at a proximal end of the enclosure body that is dimensioned to surround a base of the pull handle butterfly valve. The lock hole is configured to receive a locking member and thereby secure the device in a closed position on a handle of the pull handle butterfly valve. The blocking wall borders or is near to the opening and is configured to engage the pull handle butterfly valve when the enclosure body is secured in a locked position, thereby preventing removal of the device from the handle and the handle from being operated.
