Accurate upstream pressure control for analytical and industrial applications
Parker Porter back pressure regulators are designed for situations where stable upstream pressure is essential. They are widely used in analytical instrumentation, research environments and industrial processes where small pressure variations have a large influence on measurement results or process stability.
The Model 9000 is a compact, extremely accurate back pressure regulator with a soft seat, excellent control at low flow and very finely adjustable pressure control.
How does a back pressure regulator work?
A back pressure regulator monitors and controls the pressure on the inlet side (upstream).
When the pressure rises above the set point, the regulator opens in a controlled way.
As soon as the pressure normalises, the regulator closes.
The device therefore functions as a precision relief valve, but with much higher accuracy and adjustability.
This keeps the upstream pressure constant, even with varying flow or changing process conditions.
