Gas pressure regulator RDU

Gas pressure regulators of the RDU type are designed to reduce and automatically maintain gas pressure “after itself” using the set value.

Gas pressure regulators of the RDU type are used at the facilities for main gas pipelines:

  • Gas distribution stations.
  • Gas purification and dehydration installations.
  • Compressor stations.
  • Gas fields.

Static single channel regulators are made in the climatic version “U” category 1 according to GOST 15150-69.

Regulators are designed for operation at ambient temperatures from +50 C to -40 C and relative humidity up to 95% at a temperature of +35 C.
