Ross Controls 2783B5055 Pneumatic Lockout Valve

Ross Controls 2783B5055 is a 27-series, 3/2 piloted manual lockout valve (L-O-X) engineered for pneumatic energy isolation in industrial equipment, providing a compact inline solution that blocks a single pneumatic circuit and enables safe maintenance by isolating the energy source from downstream components. This valve combines a manual padlock-capable lockout with options for remote actuation (electrical or pneumatic) to control machine start-up and shut-down without bypassing safety interlocks, helping facilities meet lockout procedures and reduce the risk of unexpected machine movement during servicing. The 3/2 configuration denotes three ports and two positions, a common arrangement for isolating a circuit while allowing piloted control to influence downstream operation. As part of the L-O-X energy isolation family, the 2783B5055 is designed for visibility and reliability in safety-critical pneumatic systems, supporting standard workflows in manufacturing environments such as automation, packaging, and material handling where a clear, lockable energy shutoff is required for worker protection during servicing.
