In a low pressure control switch, how can you calculate the cut out valve value?

When dealing with a low pressure control switch, the cut out value is determined by understanding how the cut in and differential pressure relate to each other. The cut in pressure is the level at which the system starts operating, while the differential is the range of pressure that allows the control switch to function correctly.

To find the cut out value, you need to subtract the differential from the cut in pressure. This reflects the fact that the control switch is designed to turn off (cut out) when the pressure drops below a certain threshold, which is established by the initial cut in point minus the differential range. Therefore, the calculation effectively sets a lower limit for operation based on the differential set.

In practical applications, this means if you initiate the system at a specific pressure and monitor the differential, the system will safely disengage when the pressure drops to a level that accounts for this differential, ensuring both efficiency and safety in operation.
