Dimensions

Depending on valve size.

Description

As an alternative for integral valve locks it is also very well possible to use bolt locks for valve interlocking. A mounting system is designed for each valve depending on the type and size of the valve. Besides the economical benefits and the fact that the original lever of the valve is maintained, it has another great advantage. You can install all brackets on the valves before plant start up and you are still able to freely operate any valve as you like. For example closing all valves at the same time for testing of the plant. After you have set up your final valve positions simply mount the bolt locks on each applicable position using a special tool and two M8x30 coded bolts.
Alcatraz bolt locks fits on all type of handwheel and lever operated valves such as gate valves, globe valves, ball valves plug valves, butterfly valves and all gear operated valves. A bolt lock is mounted on the mounting system for each locked open and/or locked closed position of the valve. Their applications includes changeover of pressure relief valves, loading and unloading of pig traps, sampling devices etc.
