Valve Lockout Devices are used to close off many kinds of pressured valves to ensure that the machinery that is valve operated remains switched off while workers carry out the maintenance work. The Valve Lockout Device is attached over the operational part of the valve, before securing it in place with padlocks or hasps.
There are many types of valve lockout devices with the main ones being:Gate Valve Lockout Device – these lockout devices completely cover the valve thereby preventing access to the valve.
