Process Interlocking

Netherlocks valve interlocks eliminate human error by only allowing the right valves to be opened or closed in the correct sequence, leading operators safely through strict work procedures. Once the proper steps have been identified Netherlocks will supply mechanical valve interlocks that can be operated by means of a linear key. A Netherlocks valve interlock guides the operator through a predefined sequence with unique keys for each step.
