The MATHESON 2210 Series adjustable, miniature, dual-stage (first stage piston, second stage diaphragm) pressure reducing regulators are designed for precise, low-flow gas delivery. Their compact, dual-stage design provides precise, stable delivery pressures even as the supply pressure decreases. The MATHESON 2210 Series regulators control inlet pressures up to 3000 PSIG and have a flow capacity Cv of 0.04. The MATHESON 2210 Series regulators are available in a wide variety of configurations, making them ideal for use in labs, industrial monitors, disposable / transportable gas cylinders, and for the regulation of a broad range of media.

Applications

Low flow applications requiring high-purity gases and a compact regulator due to space limitations.
