The IR4000 regulator offers high pressure capability with an inlet pressure up to 4,000 psig, and functions equally well with low supply pressure for point-of-use applications. The IR4000’s design characteristics such as a large convoluted Hastelloy C-22® diaphragm and a unique compression member give you precise control and consistent performance over the operational range of the regulator. Superior internal component alignment and contamination control make the IR4000 the perfect solution for your general purpose pressure regulator needs.
