MAIN CHARACTERISTICS of
Direct acting pressure regulator RTG 311

RTG 311 pressure regulators are included within the direct acting and balanced valve regulators class. The regulator is used for reducing and regulating the pressure of natural gases and LPG, ensuring a constant value of the outlet pressure within the limits of the regulating class, irrespective of the fluctuations of inlet pressure and flow rate.
Reference standards: EN 334 and EN 14382
CE Certificate according to PED 97/23/EC
