Gas pressure regulators RD-M are designed to reduce and automatically maintain the gas pressure “after itself” at the set value.
Gas pressure regulators of RD-M type are used at the facilities of main gas pipelines such as gas distribution stations, compressor stations, etc.
The regulators are made in the climatic version “U” category 3 or in the version “XL” category 3 according to GOST 15150-69.
Nominal pressure, 6,3 (63) MPa (kgf/cm²): RD-M 63/15, RD-M 63/25, RD-М 63/40, RD-М 63/50,RD-М 63/80, RD-М 63/100, RD-М 63/150.
Nominal pressure, 10,0 (100) MPa (kgf/cm²): RD-М 100/15, RD-М 100/25, RD-М 100/40, RD-М 100/50, RD-М 100/80, RD-М 100/100, RD-М 100/150.
