Johnson Controls P70GA-27 Pressure Control 30067439-890 making it effective for stagingThe Johnson Controls P70GA 27 is a dual circuit low pressure control engineered for precision monitoring in commercial refrigeration, HVAC, and pneumatic systems. This unit features a versatile 20 to 100 PSI pressure range and an open low operation (opens on pressure drop), making it essential for compressor protection and system cycling. The hardware includes a 4 wire 2 circuit configuration with one normally open (NO) and one normally closed (NC)
