Norgren has developed a stackable lock-out valve to help machine builders and end users comply with the new SEMI safety standard S2-0200. The lock-out tag-out valves provide a simple and inexpensive solution allowing the pneumatics on cluster machines to meet the required standard and continue efficient production. Each valve on the panel can be configured to individually control one chamber of the machine. This means that the compressed air supply to pneumatic tools in one chamber can be safely shut off during maintenance while the remaining chambers continue production. Multiple valves can be actuated simultaneously by using an optional cross bar to shut down more than one chamber or a chamber and the main air supply. Three-way manually operated, lockout valves can be locked in the closed position with a standard lockout hasp with a lock shackle diameter up to 8mm. In the closed position, the valves shut off the airflow between the inlet and outlet ports and exhaust the downstream air.
