Flow regulators are used to maintain a defined flow rate regardless of
pressure variations of the supply line. Precise flow control in process
system performance and in the case of plumbing systems, it provides
comfort of use at low pressure as well as water and energy saving at
high pressure. When there is no flow or pressure, the o-ring is
relaxed. When there is normal pressure, the o-ring sujected to the line
pressure is compressed into the seating area. As the pressure
increases, the o-ring is compressed further into the seating area. As
the pressure decreases, the o-ring relaxes. Since the flow rate for a
given orifice changes to the square root of delta P, the o-ring
deformation is equal to this this giving a constant flow over a ride
range of pressure variations.
