Controllers: Direct vs. reverse-acting control
Controllers: Direct vs. reverse-acting control

14/3/2014, · For example, if a back-pressure controller (where a control valve opens to decrease the pressure measured upstream of it) sees a rise in pressure, it should increase its output. Increase measurement/increase output is "increase/increase" or direct-acting. In contrast, nearly every flow controller I've seen is "increase/decrease" or reverse-acting. Mr.
