Ross Controls Y1523C4002 NSNBC01 Lockout Valve, part of the 15 Series Classic line, is a manually actuated 3/2 L-O-X energy isolation valve designed to safely lock pneumatic circuits during maintenance. The aluminum-bodied valve uses a stainless steel spool and fluorocarbon seals, with 1/2 in NPT inlet and outlet ports and a 3/4 in exhaust, delivering Cv ratings of 7.1 between ports 1-2 and 4.0 between ports 2-3 (roughly 7,000 and 3,900 NL/min respectively). It is rated for Safety Category 1 with PL c, and carries an EAC declaration; DGUV certification and CE certification are not provided, while CSA/UL certification is not listed. Typical applications include isolating actuators, valves, or cylinders in manufacturing and processing lines during maintenance, where a compact inline lockout valve is required to ensure safe re-energization control. The NSNBC01 designation appears as part of the model code within the Y1523C4002 family.
