Smarter Valve Locks
Netherlocks (Houston, TX) is now offering mechanical valve interlocks that eliminate human error to ensure that critical valves are locked in the proper position. The interlocks are operated with two color-coded keys, which control the open and closed positions of a valve while communicating the current state. When the green key is released, the valve is locked in the “locked-open” position. For the red key to be released, the valve must be locked in the “locked-closed” position. In addition, the interlocks are fully mechanical, which eliminates the need for electrical wiring.
