Gas pressure regulators of the RDU-T type with a heat generator are designed for automatic regulation of gas pressure “after itself” of the set value at the facilities of high pressure gas pipelines.
They are used at:
Static single channel regulators are made in the climatic version “U” category 1 according to GOST 15150-69.
The 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.
The RDU-T regulators differ from the RDU regulators of the same class by the heating of the shut-off and regulating device in the zone of gas throttling using specially mounted heat generators which operate without an external energy source by taking a part of the kinetic and potential energy of the compressed main gas.
The heating temperature is sufficient to prevent hydrate formation processes.
