| Company information
The Pressure Independent Characterized Control Valve consists of a differential pressure regulator in series with a characterized control valve. The amount of flow that passes through the valve is controlled by the pressure regulator, which moves according to the change in the pressure above and below it. All pressure changes are absorbed by the pressure regulator, allowing the differential pressure to be held constant over the control valve section, according to the company.
