Valve Lockouts

Match the device to the handle. A ball valve has a lever: the Universal Ball Valve Lockout clamps over the lever in the closed position. A gate valve has a wheel: the Gate Valve Cover covers the whole wheel so it cannot be turned. A butterfly valve has a lever with a trigger: the Butterfly Valve Lockout blocks the trigger. Check the handle length or wheel diameter on the product page.

Gate valve covers come in sizes from 25 mm to 330 mm wheel diameter; the Adjustable Gate Valve Cover opens up to fit wheels in between and takes several padlocks. For very large wheels, or valves with an unusual handle, a cable lockout threaded through the spokes and around the pipe does the job: see the cable lockout devices linked above.

Most valve lockouts are polypropylene or nylon: they do not rust, shrug off most process chemicals and work from about -30 to +80 °C. Where the device may be struck or heated, the steel ball valve lockout adds a steel cover. Pair any of them with a nylon or aluminium padlock outdoors so the lock does not seize.
