A safety valve mounted in a steam cleaner is provided. The safety valve comprises a cap assembly, an actuation assembly, and a lock assembly. A rotation of the cap is adapted to detach the cap assembly when the steam cleaner is not operating or steam pressure inside the steam cleaner has not reach a safety value since the legs of the clutch are engaged with the notches of the driving disk. Responsive to generated steam reaching the safety value, the steam passes through the valve to lift the pushing member for compressing both the actuating member and the spring and disengaging the legs from the notches prior to exiting the steam cleaner such that rotating the cap will not rotate the lock assembly.
