MAIN CHARACTERISTICS of
Direct acting pressure regulator RTG 406

RTG 406 regulators are of direct action type and are intended for low flow rates. These regulators are used for reducing and regulating the pressure of natural gases and LPG and they ensure constant maintenance of outlet pressure within the regulating class limits, irrespective of the variations of inlet pressure and flow rate. They are designed for natural gas transportation and distribution networks.
Reference standards: EN 334 and EN 14382
CE Certificate according to PED 97/23/EC
