Johnson Controls P74BA-1 Pressure Control 30067439-890 though it must not beThe Johnson Controls P74BA 1 is a robust differential pressure control designed for demanding commercial HVACR applications, including chiller proof of flow and refrigeration compressor lube oil monitoring. Engineered with stainless steel bellows, this SPST pressure switch effectively measures the variance between two sensing points, opening the circuit on a decrease in pressure difference. This action is critical for protecting equipment from low
