( full specifications are in the manual for the device )

1. Pressure regulators belong to the group of intelligent devices and are designed to stabilize the initial pressure at a given level or limit the gas flow through the regulator at reduction of pressure by forming control actions based on the result of measurements of the initial pressure.
    Compared to existing regulators, this regulator has such significant advantages as a wide range adjustment from 5 to 95%, higher accuracy and quality of adjustment. The accuracy of maintaining the pressure at the outlet of the regulator reaches one percent of the set pressure.
2. The regulator can be used as a stand-alone device or a functional link in an automatic control system technological equipment of the GDS, for example, in the control complexes of the gas heater and the gas reduction unit. The regulator can also be used as a shut-off valve.
3. When using the regulator as a stand-alone device – in this case the regulator is equipped with a processing controller measurement results of the control pressure and pressure at the outlet of the regulator According to the measurement result, according to the specified algorithm, control actions are formed on the solenoid valves of the regulator.


1. Regulators depending on the nominal diameter (DN) of the control valve the following modifications are indicated: IRD-05-25/64, IRD-05-50/64, IRD-05-100/64, IRD-05-150/64 and IRD-05-200/64.
2. Maximum gas volume flow through the regulator at an inlet pressure of 6.4 MPa – from 5,000 to 400,000 m3/h (depending on the diameter of the remote control valve).
3. The maximum excess gas pressure at the regulator inlet is 6.4 MPa.
4. Regulators are designed for operation outside hazardous areas. and indoors at an ambient temperature of minus 30 to plus 50 °C.
5. Overall dimensions (depending on the modification of the regulator):
– minimum dimensions 165 x 150 x 125 mm,
– maximum dimensions 430 x 300 x 200 mm
6. Weight – from 8.8 to 61.5 kg (depending on the modification of the regulator).
7. The service life of regulators is at least 10 years.


1. Regulators can be placed outdoors or indoors directly on the pipeline in any position.
2. The company provides warranty service for the regulator within 24 months and after-sales service throughout the service life.
