Two-stage pressure regulator for cylinder, suitable for use with pure gases, equipped with two pressure gauges to show cylinder pressure and operating pressure.The device is made up of two HF pressure reducers with chemically nickel-plated CW617N brass bodies and integrated overpressure discharge valves: the first reduces the cylinder pressure to a fixed pressure of 12 bar, the second allows the user to adjust the outlet pressure between 0.2 bar and 2 bar.The dual stage system is designed to optimally stabilize the regulator’s outlet pressure and should be chosen for operating pressures lower than 2 bar and that require stable and precise dispensing.Maximum inlet pressure is 200 bar, the outlet pressure is adjustable up to 2 bar.Inlet connection is specific to the gas type (see table), outlet connection is G1/4″ M R.Its maximum capacity at 2 bar outlet pressure is 2,4 Nm³/h, 40 Nl/min.At the customer’s request it is possible to carry out a helium leak test at 10-4 mbar l/s.
