MAIN CHARACTERISTICS of
Direct acting pressure regulator RTG 320

The pressure regulators included in the RTG 320 family are direct acting regulators with balanced valve. The regulators are used for reducing and regulating the pressure of LPG and natural gases, ensuring a constant value of the outlet pressure, within the limits of the regulation 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
