Model 3590

Model 3590 single-stage ultra high-flow regulator with auxiliary high-pressure gauge port for low pressure cylinder applications and stainless steel diaphragm used in pipeline, manifold and bulk systems.


Model 3590 is a single-stage, ultra high-flow, pipeline regulator. It is designed specifically for applications demanding extremely high gas flows, even at low incoming pressures. Model 3590 features eight functional body ports, two 1/2" NPT and six 1/4" NPT ports that can be used for a wide variety of inlet/outlet and gauge location configurations. Its auxiliary HP gauge port allows the Model 3590 to be used for low pressure cylinder applications.
