Fire-proof interlock
The MRL Multi Rotation Lock from Netherlocks, for multi rotation handwheel -operated valves, has been thoroughly tested and awarded the Fire Test Certificate according to ANSI/API and ISO standards.
This means that even in the event of a fire it will continue to function safely as intended, and will not cause additional disruption to the normal procedure of operation afterwards.
The interlock was subjected to temperatures of nearly 1000°C for around 20 minutes, and after cooling back down functioned correctly to safely lock and unlock the handwheel valve according to specification.
