22、omponents designed to maintain the pressure of the gas at an approximately constant level.It is therefore necessary to know some performance characteristics of these components in order to determine their suitability for an application.

23、015Pneumatic fluid power Compressed air pressure regulators and filter-regulators Part 1: Main characteristics to be included in literature from suppliers and product-marking requirements1 ScopeThis part of ISO 6953 specifies which characteristics of compressed air pressure regulators are to be incl

24、uded in literature from their suppliers. It also applies to filter-regulators.This part of ISO 6953 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.

25、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); an

26、d 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 = 105Pa; 1 MPa = 1 N/mm2.The rated pressure should be selected from the preferred pressures listed in ISO 2944.NOTE 2 The m

45、nd filter-regulators shall be classified according to their rated pressure, selected from ISO 2944.The rated pressure shall be verified using the test procedure specified in ISO 6953-2: 2015, Clause 6.

46、 the limitation that can be imposed by the diaphragm. The range of duties and sensitivities of the diaphragm used vary widely and their strength can be limited to achieve the accuracy required by the application.4.2.4 Range of operating temperatures4.2.4.1 The temperature range in which the material

47、 and the operation of the pressure regulator and filter-regulator are not impaired shall be stated.4.2.4.2 Other combinations of pressure and temperature ratings for optional designs that could require a different rating shall be specified.4.3 Particular requirements4.3.1 GeneralThe data provided by

48、 the supplier shall assist the user in selecting the compressed air pressure regulator and filter-regulator best suited for the particular application.4.3.2 Adjustable pressure ranges (outlet regulated pressure)The upper limit of the recommended adjustable pressure range should normally be chosen fr

49、om the following preferred ranges but not to exceed the inlet rated pressure: up to 100 kPa (1 bar); up to 200 kPa (2 bar); up to 400 kPa (4 bar); up to 800 kPa (8 bar); up to 1 000 kPa (10 bar); up to 1 600 kPa (16 bar).Special ranges can also be available.The adjustability of the upper limit of the pressure range is a minimum and the upper limit should not be regarded as a limiting pressure.
