The BPR regulates upstream pressure for analytical measurement sensors. The back pressure relief valve is made of 316 SS and is suitable for high pressures and temperatures. The valve utilizes threaded 1/4″ NPT process connections. When redundant analyzers are on the same sample source, the backpressure relief valve provides constant inlet pressure, which allows an operator to shut off analyzers without varying the pressure and flow of the rest. When the sample pressure increases, the valve opens wider to maintain pressure at the adjustment point and improve the flow-through. When the sample pressure reduces upstream, the valve reduces the flow path orifice to maintain pressure and reduce the flow. If the pressure in the stream reduces below the valve adjusting point, the valve will not function because it can not detect flow at the outlet connection. Lastly, this valve is available as part of a sample conditioning panel or as a component for existing panels.
