Ross Controls YD1523C3002 Manual Pneumatic Lockout Valve

Ross Controls YD1523C3002 is a 15 Series Manual Lockout L-O-X valve engineered for pneumatic energy isolation in industrial environments. This BSPP-thread version (the D prefix denotes BSPP; for NPT threads, the non‑D model Y1523C3002 is available) is a 3-way, 2-position valve that, when shifted to the closed position, simultaneously blocks the air supply and exhausts downstream pressure, making it ideal as the first valve in a machine’s air line during maintenance. The configuration for this model features 3/8 inch inlet/outlet ports and a 3/4 inch exhaust, with an approximate weight around 1.5 lb (0.7 kg). Built for reliability in safety-critical work, the standard construction employs an aluminum body, a stainless steel spool, and fluorocarbon seals to withstand routine plant use. Designed to support lockout/tagout safety programs under OSHA 29 CFR 1910.147, this valve is commonly deployed to prevent unexpected machine restart by isolating the upstream supply while venting downstream pressure when secured in the off position.
