01. RDP pressure regulators
- Purpose:
Piston pressure regulators and reduction units based on them are designed for throttling high-pressure gases and liquids and automatically maintaining the pressure in the outlet pipeline of predetermined pressure without fluctuations, regardless of the gas withdrawal by the consumer and changes in the inlet pressure. They work using the energy of the medium.
Medium: gases and liquids, including aggressive ones
Non-volatile: Inlet pressure up to 14.0 MPa (140 kgf / cm2)
02. Piston pressure regulators
- Purpose:
Piston pressure regulators (shut-off pressure control valves) have the same principle of operation as the RDP, but a different design: maintenance during operation does not require regulator (valve) dismantling ,which is crucial for the objects of large dimensions. Lower inlet pressures and mass-produced moulded cases reduce the cost of RDP (SPCV).
Medium: gases and liquids, including aggressive ones, steam
Non-volatile: Inlet pressure up to 4.0 MPa (40 kgf / cm2)

Our Products
Orgenergogaz company has successfully carried out RDP regulators acceptance tests at Saratovorgdiagnostika testing ground .
The regulators are approved for use at the facilities of Gazprom and are included in the "Register of equipment with technical specifications conforming to Gazprom's technical requirements."
The regulators are protected by patents and have certificates of conformity. New approaches in the development, design and manufacture of RDP regulators have made it possible to get significantly better results than the ones of all known analogues:
- Minimum gas consumption (from 1 m3 / hour) without outlet pressure fluctuation. Thus, a separate low-flow system is no longer necessary;
- Resistance to the aggressive effects of polluted gas;
- Made of stainless steel;
- RDP regulators are the smallest in size, they are way better than any analogues when it comes to weight to dimension ratio.
- Easy installation and operation;
- Reliable valve closure and low gas pressure gain at zero flow ("dead end");
- Significant reduction of metal and material consumption;
- Versatility, efficiency and aesthetics
- Ensured safety during the entire operation period;
- In the regulator there is used the system that allows to significantly reduce the unevenness of regulation and achieve high flow rate, which is especially important for seasonal changes;
- The use of a piston in the regulator with a sufficient active area and a minimum number of friction parts increases the accuracy and reliability of operation
- Full import substitution.
The regulators are used:
- in gas pipeline systems as a part of gas distribution stations
- in gas treatment units at compressor stations
- at the oil production facilities, in oil and gas industry
- at industrial enterprises
- at power engineering facilities
- in water utility systems
- in heat networks
Areas of application of RDP regulators:
- Gas distribution stations (GDS) that are the part of the main gas pipeline
- Fuel gas treatment units (BPG) at compressor stations
- As a part of associated gas treatment systems and units
- Gas distribution stations for servicing automatic gas-filling compressor stations (CNG stations)
