Automation Components Inc (ACI) 127210 Valve L99H008 Always match the CNT3671 ratingThe ACI 127210, also known by the manufacturer part number PXP2. 3FS, is a high performance electric to pneumatic transducer designed for precise pressure control in commercial HVACR systems. This dual valve pneumatic transducer converts an analog electrical input signal into a proportional pneumatic output, ranging from 0 to 15 PSI. Unlike single valve models, the dual valve design does not consume air at the set point, significantly reducing air
