This valve meets the standard for installation conducted by an operator specified by OSHA. When the machinery is maintained and serviced, the purge valve (safe on-off valve) shall be used to eliminate the remaining pressure when the air source is cut off. During this operation, the unconscious operation of a third party will cause pressurizing of the end of the pipeline and sudden machinery actuation of the cylinder and other devices, which will cause operator injuries. Therefore, it is stipulated that all the operations for this aim must be added with a lock to prevent the operator injuries caused by the unconscious operation of a third party.
