® L-O-X (Lock Out & eXhaust) Valves ® ROSS L-O-X valves are energy isolation valves and are � �� �� � generally used as the first valve in a line supplying com- pressed air to equipment. Air can be shut off by pushing the 2 ® 12 10 red L-O-X handle inward; downstream air is simultaneously Y3 ® exhausted through the L-O-X exhaust port. OSHA compli- ance requires that the valve be padlocked in this position to 2 1 3 prevent handle from being pulled out inadvertently during MANUAL maintenance. 3 1 � ® Piloted L-O-X valves allow the flow of air to be controlled ® remotely as long as the L-O-X control is open.
