The gas overpressure regulators ALz-6U are determined for the single-stage automatic regulation of inlet overpressure of natural gas to lower outlet overpressure.
Outlet overpressure is kept in the specified tolerance with regard to the gas demand quantity, gas pressure fluctuation in pipeline and other adverse effects.

- valve body of grey alloy, other cast stocks of aluminium alloy,
- in-built safety valve,
- in-built emergency shut-off, which will close permanently the gas inlet to the regulator at gas overpressure
  drop or increase over the specified limit,
- the regulator is demountable, repairable,
- the service is secured,
- the single parts of the regulator are made out of materials resistant to the gas effects,
- the screen against impurities penetration in the regulator is the part of the regulator,
- the flanged connections enable easy assembly and disassembly of the regulator,
- possibility of the transformation from the type AB to BD and CE.
