Alcatraz Interlocks introduces the world's smallest multiturn valve interlock
The first key can only be released in the fully open position the other key can only be released in the fully closed position

The DML-S is specially designed to fit on all small types of hand wheel operated valves such as gate and globe valves, bar stock, screwed or bolted bonnet valves

They are mounted on multi-turn valves to interlock the locked open and/or locked closed position of the valve. Only if both keys are inserted in the lock portions the valve can be operated. The first key can only be released in the fully open position the other key can only be released in the fully closed position.

Their applications include requiring throttling and frequent operation and on off applications so called Shut off. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken.

Since its founding in 1993, Alcatraz has developed into an international operating company with representations worldwide. The company produces a wide range of interlock systems and related services that meet the highest quality requirements. The main office is located in the Netherlands.
