MOV Locks
Alcatraz MOV (Motor-Operated Valve) Locks provide dedicated interlocking solutions for motor-operated valves within actuated sequences (often in pigging) and other complex process procedures.
By integrating MOV operation into the sequential interlocking logic, MOV Locks ensure that motor-operated valves can only be operated when the correct procedural conditions have been met preventing unauthorised or out-of-sequence valve movements.
