MID-POSITION

The final position of the valve is mid-positioned, sometimes referred to as cracked. In this position, refrigerant is allowed to flow through the system as normal yet the service port is still opened.

The technician can connect gauges to the service port or ports (with the valve back seated) then crack the valve to monitor system operation (either or both suction line and discharge line) while the system is running.
