The IR5000 Series regulator offers high pressure capability with an inlet pressure up to 3,500 psig. The larger convoluted Hastelloy C-22® diaphragm provides greater sensitivity over the operational range making this regulator ideal for precise outlet pressure control. Close tolerances and tight alignment of moving components minimize hysteresis and improve cycle life. Convoluted, Hastelloy C-22® diaphragm provides high corrosion resistance and increases cycle life.
