Johnson Controls P74BA-1C Pressure Control

The P74BA-1C Pressure Control from Johnson Controls delivers precise differential pressure sensing for reliable HVAC and industrial systems. This adjustable differential pressure control provides an operating pressure range of 8 to 70 PSIG and a differential range of 8 to 30 PSI, designed to respond quickly to changing system demands.

With SPST contacts and broad electrical compatibility, it suits differential pressure sensing applications across equipment such as air handlers and process controls. The compact, 1/4 inch female flare connection ensures straightforward installation. Engineered for reliability, the P74BA-1C maintains stable control across a wide temperature range and continuous-duty environments, while its adjustable differential setting supports precise threshold tuning for fans, dampers, and compressors.
