Ross Controls 1523C5002 L.O.X. Valve

Ross Controls 1523C5002 L.O.X. is a 3/4‑inch, manual lockout valve in the Series 15 L‑O‑X family, engineered as a 3/2 pneumatic energy‑isolation device that shuts off the upstream air supply and exhausts downstream pressure when the handle is moved to the closed position. The valve body is cast aluminum and ports are NPT by default, with options for piped exhaust and other exhaust/configuration suffixes indicated by the model number. The Y1523C5002 designation corresponds to a Classic 15 Series 3/2 lockout valve with 3/4‑inch ports, and standard literature lists a weight of approximately 2.5 lb (about 1.1 kg) for this configuration. Ross describes manual lockout L‑O‑X valves as generally used as the first valve in a line supplying compressed air, making them well suited for safe maintenance and energy isolation in industrial pneumatic systems.
