Gate valves tend to be operated manually via a handwheel. If the handwheel is less than 350mm diameter you can use a valve wheel lockout device, secured in place with a safety padlock.
If the valve hand wheel is larger than 350mm, you can use a length of chain wrapped around the handwheel rim or spokes then arond the bonnet of the valve or some adjacent pipe or steel work.
Also useful for locking large handwheels is a safety cable lockout.
For more information about locking valves, read our technical article.
