Certified Fire-Proof
02 July 2013
The MRL Multi Rotation Lock from Netherlocks has been thoroughly tested and awarded the Fire Test Certificate according to ANSI/API and ISO standards, so customers can be assured that even in the event of a fire it will continue to function safely.
The interlock was subjected to temperatures of almost 1000°C for 20min and, after cooling down, functioned correctly to safely lock and unlock the handwheel valve according to specification.
The test, performed by Yarmouth Research and Technology, LLC, found the MRL to be compliant with ANSI/API Standard 607 Sixth Edition – 2010 and ISO 10497:2010. During the test the lock was burned with one key in the lock; after cooldown the lock remained securely locked unless both keys were inserted, whereby it unlocked and operated smoothly as intended.
Netherlocks’ MRL is an interlock for multi rotation handwheel-operated valves. It allows the handwheel to be turned only when two keys are inserted into the lock, ensuring that it can be operated only when it is safe to do so.
