Full Description

This part of ISO 6953 specifies the characteristics of compressed air pressure regulators to be included in literature from their suppliers. It also applies to filter-regulators.

In addition, it specifies the product marking requirements for pressure regulators and filter-regulators.

This part of ISO 6953 is applicable to compressed air pressure regulators with a rated inlet pressure of up to 2500 kPa [25 bar¹⁾] and an outlet adjustment pressure of up to 1600 kPa (16 bar), and to filter-regulators with rated inlet and outlet pressures of up to 1600 kPa (16 bar), in which the major contaminants are removed by mechanical means. The maximum temperature is 80 C for regulators and filter-regulators and applies to materials of construction that are light alloys (aluminium, etc.), zinc die-casting alloys, brass, steel and plastic.

The rated pressure should be selected from the preferred pressures listed in ISO 2944.

1) 1 bar = 0,1 MPa = 10⁵ Pa; 1 MPa = 1 N/mm².
