Application
PGB-15V-2-0.6-OG-U1-SG gas regulating unit are designed for gas purification from mechanical impurities, commercial gas flow measuring, pressure reducing from high to medium and automatic maintenance of the pressure within the specified limits, automatic gas supply shut-off during an emergency increasing or decreasing of outlet pressure beyond allowable values, automatic collection, recording and remote transmission of information about the unit operation. The unit is applied in gas distribution and gas consumption systems.
Specification
The unit is designed for operation outdoors in macroclimatic areas with moderate climate (N) and the 1st location category.
Designed snow load 120 kgf/m2 conforms the requirements of the 2nd territorial area; wind load 38 kgf/m2 as well conforms the requirements of the 3rd territorial area.
In the compartment with processing equipment explosion hazard area class is V-1a and complies with the requirements of the Russian Electrical Code (PUE).
Fire hazard category of the unit complies with the Russian fire safety regulations NPB 105-03:
– processing compartment – A;
– in compartment with control instruments and automation and heating –G.
