> This pneumatic back pressure regulator maintains a constant upstream pressure by automatically throttling the flow based on real-time pressure measurements. It continuously senses the pressure and adjusts the valve opening to stabilize against load changes, making it an automatic regulating instrument. As a pneumatic device, it falls under tariff item 9032.81.00.
