Abstract Preview

ISO 6953-1:2015 applies to

- manually controlled direct operated types (with or without relieving mechanism),

- manually controlled internal pilot operating types (e.g. nozzle flapper), and

- external pilot operated types.

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 2 500 kPa (25 bar) and an outlet adjustment pressure of up to 1 600 kPa (16 bar); and to filter-regulators with rated inlet and outlet pressures of up to 1 600 kPa (16 bar), in which the major contaminants are removed by mechanical means.

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

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

NOTE 2 The main characteristics to be included in the supplier's literature related to electrically modulated pneumatic continuous pressure control valves are specified in ISO 10094‑1.
