Johnson Controls P70AB-2C Pressure Control SPST Adjustable Differential 70-50 PSI

The Johnson Controls P70AB-2C Pressure Control is a universal component for precise pressure regulation in HVAC systems that has replaced the P70AA-4. It has an SPST configuration and can change pressures ranging between 20-100 PSI, with a variable differential range of 70-50 PSI. This is useful for maintaining the desired conditions of operation of air treatment equipment or temperature control systems and/or giving assurance to compressor equipment of efficient running and optimization of its life. The main benefit is its capability to mitigate the risk of over-pressurization of the system hence conserving energy and minimizing the likelihood of equipment failure.
