Master Lock Ball Valve Lockout

The Master Lock Seal Tight Handle-On Ball Valve Lockout secures a ball valve handle in the off position to support lockout and tagout procedures. It is built for maintenance teams and facility operators who need a straightforward mechanical lockout device for quarter-turn valves. The unit is supplied as a single piece ready for immediate use.

Suits standard handle-on ball valves

This device fits directly onto the existing handle of a ball valve, so it suits plants where valves already have lever handles installed. It is not for gate valves, butterfly valves or valves with missing or non-standard handles. Buyers who need a lockout for a different valve type or a handle-less ball valve should look at another solution.

Handle-on ball valve attachment method

The defining specification is the handle-on mounting style that clamps onto the valve's own lever. This attachment method decides whether the lockout matches the installed hardware. Confirm that the target valve has a standard lever handle before ordering.

Questions about this item

How do I pick the right size for my ball valve handle?

The Seal Tight Handle-On design fits directly over the existing handle on compatible ball valves, so choose the lockout that matches your valve handle dimensions.

What does the lockout do once it is fitted to the valve?

It encloses the handle to prevent the valve from being turned, providing a physical barrier that supports lockout/tagout safety procedures.

Does this lockout work with a specific locking standard or shackle size?

It accepts standard safety padlock shackles, allowing multiple authorised users to apply their own locks for group isolation.
