1. PC — series.
2. Connection size, inches or maximum flow capacity, ncm3/h (only for the version of KD regulator):
6: 6 ncm 3/h;
10: 10 ncm 3/h;
25: 25 ncm 3/h;
50: 50 ncm 3/h.
3. Maximum operating pressure:
1 — 1 bar;
6 — 6 bar;
0,5 — 0,5 bar (only for zero pressure and gas-air pressure ratio regulators).
4. Specifications or type of the regulator:
В - regulators-stabilizers standard version;
С - regulators-stabilizers with built-in safety relief valve;
К - regulators-stabilizers combined with safety shut-off valve;
Н - version of zero pressure regulator;
А - version of gas-air pressure ratio regulator;
КD - version of combined regulator with built-in SRV and SSOV.
5. Code of regulator’s version (three-unit code):
0 Х Х - three-unit code for standard regulator (it indicates outlet pressure range);
1 Х Х - three-unit code for regulator with built-in SRV (it indicates outlet pressure range and actuation adjustment of SRV );
2 Х Х - three-unit code for combined regulator with SSOV it indicates outlet pressure range and actuation adjustment of SSOV );
3 Х Х - three-unit code for combined regulator with SSOV and built-in SRV ПСК (it indicates outlet pressure range and actuation adjustment of SSOV and built-in SRV);
4 Х Х - three-unit code for combined regulator with SSOV and SRV in separate housing (it indicates outlet pressure range and actuation adjustment of SSOV and SRV).
For gas-air pressure ratio regulators should be additionally specified the versions:
- 1 - gas-air pressure ratio regulators 1:1;
- 2 - gas-air pressure ratio regulators (gas pressure is less than air pressure Рair / Рgas ≤ 10);
- 3 - gas-air pressure ratio regulators (gas pressure is more than air pressure Рgas / Рair ≤ 2).
For zero pressure regulators (РС...-Н), gas-air pressure ratio regulators (РС...-А) and combined regulator with built-in SRV and SSOV (РС...-КD), the controlled range of the outlet pressure is not specified.
For regulators of KD version should be additionally specified the housing version:
- angle connection;
- angle connection from the bottom upwards;
- linear connection;
- U-shaped connection.
6. Climatic versions:
- (-30...+60 °С);
- (-40...+60 °С).
7. Manufacturer’s declaration: ТУ BY 200020142.030-2013.
According to the type of connection to the pipeline, the regulators can be manufactured:
- coupling - DN 15 - 50;
- flanged - DN 15 - 150.
Flanges of the regulators comply with ГОСТ 33259, type 01, PN 6 (up to 0,6 MPa).
Upon customer’s individual request it is possible to manufacture the pressure regulator DN 32 - 100 according to ГОСТ 33259, type 01, PN 16 (up to 1,6 MPa).
