Valve interlocks can only be used when both keys are inserted in the interlock. Both keys are individually coded. A key with the wrong coding cannot be inserted in the interlock respectively cannot open this. Each key can only be removed when the valve is in a certain position. Once one key has been removed, the other one is trapped in the interlock.
