Product Overview
The BAR PKN-2/0-050-C078-09 and PKN-5/4-032-C078 are pneumatic coaxial valves engineered by BAR Pneumatic (Bar Valves) for demanding industrial process control. Unlike conventional spool or poppet designs, these valves utilize a coaxial (in-line) architecture in which the actuator is mounted directly in line with the flow path, delivering a compact, pressure-balanced construction with minimal dead volume and rapid, repeatable actuation. The PKN series is designed for precise on/off control of neutral and aggressive media, offering high flow capacity relative to body size, bubble-tight sealing, and reliable operation across a wide range of industrial pressure and temperature conditions. These valves serve as critical control elements in automated process lines, test benches, and fluid handling systems where fast response and leak-free performance are essential.
