Valve Interlocking System


Alcatraz designs and manufactures interlock systems that safeguard critical installations. Each system is based on our patented key and lock design, which eliminates the chance of human error.

With an Alcatraz Interlock System, the operator must follow a predetermined sequence by means of a mechanical coded key transfrer. Our system can safeguard even the most complex operating sequences.

Alcatraz has successfully deployed systems in the oil & gas, chemical and offshore industries.
