This document describes test methods for determining the performance characteristics of electrically modulated hydraulic pressure control valves.

This document specifies methods for determining, under steady-state conditions, the pressure differential caused by the flow through any given path in a hydraulic fluid power valve. Requirements for test installations, procedures and presentation of results are specified.

This document defines an identification code for hydraulic valve mounting surfaces and for hydraulic cartridge valve cavities that are defined in other International Standards (see Bibliography). This document is not applicable to mounting surfaces and cartridge valve cavities that do not conform to these International Standards. This document does not require that the hardware be marked with the identification code.

ISO 5781:2016 specifies the dimensions and other data relating to surfaces on which hydraulic pressure-reducing valves, sequence valves, unloading valves, throttle valves and check valves are mounted in order to ensure interchangeability. It applies to mounting surfaces for hydraulic pressure-reducing valves, sequence valves, unloading valves, throttle valves and check valves, which represent current practice; they are generally applicable to industrial equipment.

ISO 7368:2016 specifies only geometrical data relating to cavities in which two-port hydraulic slip-in cartridge valves are mounted in order to ensure interchangeability. NOTE For example, this document does not specify rated pressures. It applies to cavities for two-port hydraulic slip-in cartridge valves which are generally applicable to industrial equipment.

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 t...view more

This part of ISO 5599 specifies the requirements for a mounting interface surface without electrical connector for fiveport pneumatic directional control valves, for use at a maximum rated pressure of [ 1)]. It gives
— dimensions and tolerances of the interface features,
— port identification, and
— identification of the result of control-mechanism actuation.
It is not applicable to the functional characteristics of interfaces.

This part of ISO 5599 specifies the requirements for a mounting interface surface with optional electrical connector for five-port pneumatic directional control valves, for use at a maximum rated pressure of [ 1)]. It gives
— dimensions and tolerances of the interface features,
— port identification,
— identification of the result of control-mechanism actuation, and
— dimensions, tolerances and specifications for optional interface electrical connector mating.
It is not applicable to the fu...view more

ISO 6263:2013 specifies the dimensions and other data relating to surfaces on which hydraulic compensated flow-control valves are mounted in order to ensure interchangeability. It applies to mounting surfaces for hydraulic compensated flow-control valves which represent current practice; they are generally applicable to industrial equipment.

ISO/TR 17209:2013 specifies the dimensions and provides other data relating to cavities with ISO 725 UN and UNF threads in which two-, three-, and four-port screw-in cartridge valves are mounted, in order to ensure dimensional interchangeability. It is applicable to two-, three-, and four-port screw-in cartridge valves generally used in industrial, agricultural, mining and mobile equipment.

ISO 7790:2013 specifies clamping dimensions of four-port modular stack valves and four-port directional control valves, sizes 02, 03, 05, 07, 08, and 10, on mounting surfaces. The dimensions and sizes conform to ISO 4401 so as to ensure interchangeability of these valves and to reduce the number of fixing devices to be used. It applies to clamping dimensions of four-port modular stack valves and four-port directional control valves which represent current practice. They are generally applicable ...view more

ISO 10770-2:2012 describes methods for determining the performance characteristics of electrically modulated hydraulic three-port directional flow-control valves. This type of electrohydraulic valve controls the direction and amount of hydraulic flow in a hydraulic system.

ISO 6953-3:2012 specifies alternative test methods for testing pneumatic fluid power components that use compressible fluids, i.e. gases. This part of ISO 6953 is applicable only to the decreasing flow rate part of the hysteresis curve of forward flow and relief flow characteristics. This method can be applied when: the pressure regulation dynamics of a component under test is rapid enough to be negligible, compared to the response of pressure changes during charge and discharge tests; the press...view more

ISO 16873:2011 specifies the mounting surfaces for pressure switches and gives guidelines for the standardized arrangement of the connections for pressure switches and for the mounting of plates and hydraulic valves.

This International Standard establishes a metric series of single-rod pneumatic short‑stroke cylinders with bores from 20 mm to 100 mm (inclusive) for use at maximum working pressure of 1 000 kPa [10 bar 1)] with and without magnetic function. They are not equipped with adjustable cushioning, so their application is restricted to those systems where adjustable cushioning is not required.

ISO 10094-1:2010 specifies which characteristics of electro-pneumatic continuous pressure control valves are to be included in the supplier's literature.
