Netherlocks Process interlocking

Process interlocking

A Netherlocks interlock guides the operator through a predefined sequence with unique keys for each step. It is only when a mistake is made that the operator will not be allowed to proceed and a key will not fit or a valve will be locked in position.

Netherlocks valve position indicator

Valve position indication

The Netherlocks VPI (Valve Position Indicator) provides a reliable feedback signal from hand wheel operated valves, converting the open and closed positions of the valve to a digital signal by means of a mechanical counter system.

Netherlocks FAITH

Partial stroke testing

The Netherlocks FAITH (Fail Action Integrity Test Handling) system facilitates the partial stroke testing of valves without any risk of overshoot or process interruption. The unique design means that tests can be performed at full speed, just as it would be in the event of real operation in an emergency.

Netherlocks Power Wrench

Valve operation

The Netherlocks Power Wrench has been developed as a must-have tool for opening and closing any type of manual valve within minutes. As it could take up to 1 or 2 hours to open or close very large valves, using the Power Wrench saves valuable time and takes no effort to use!
