Gas pressure regulators 149-BV

Gas pressure regulators 149-BV are designed to
for reducing and maintaining the set
pressure of natural gas, propane-butane, nitrogen and other non-aggressive gases.
The regulators are used at gas distribution stations, in pressure reducing units of gas regulator plants, etc.
Regulators provide reduction of high gas pressure, automatic maintenance of the set pressure at the outlet irrespective of changes in gas flow rate and inlet pressure, and automatic shutdown of the gas supply system.
inlet pressure and automatic shut-off of gas supply in case of emergency increase or decrease of output pressure above the permissible set values.
Regulators are characterised by high quality operation in the range of low gas flow rates.
Regulators are operated outdoors in areas with moderate climate in conditions normalised for UHL version, category I according to GOST 15150, but
at ambient air temperature from minus 40 °? with relative humidity up to 95% at temperature plus 35 °?, under the influence of atmospheric precipitations/
snow, rain/.
