Описание (английский):

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.

Overview

ISO 5783:2019 - Hydraulic fluid power - Code for identification of valve mounting surfaces and cartridge valve cavities defines a standardized identification code for hydraulic valve mounting surfaces and cartridge valve cavities that are already specified in other ISO standards. The third edition (2019) updates the codification to improve stability and extend size codes. It does not apply to non‑conforming mounting surfaces or cavities and does not require physical marking of hardware.

Key topics

Identification code structure: A five‑group code written in order and separated by hyphens:

1st group: ISO standard number that defines the mounting surface or cavity (e.g., 4401).
2nd group: two‑digit size code (based on main port diameter or screw‑in thread diameter).
3rd group: two‑digit unequivocal numbering within the referenced standard.
4th group: option sign (numeral 0 = basic version; 1–9 = options) or an asterisk.
5th group: last two digits of the year of the latest edition of the referenced standard.
Example formats from the standard: 4401–05–04–0–xx (mounting surface), 7368–11–10–1–xx (slip‑in cavity).

Size code rules: Table of size codes links two‑digit codes (00–17) to ranges of main port diameters (mm). The code is fixed when the mounting surface or cavity is first standardized; later changes to main port diameter do not alter the established size code.

Scope and limits: Applies only when the mounting surface or cavity is defined in other International Standards (see bibliography). No normative references listed; technical terms are referenced via ISO/IEC terminology resources.

Edition changes: Third edition revises the third code position logic and adds size codes 15–17.

Applications

ISO 5783:2019 is practical for:

Hydraulic component designers and manufacturers - for consistent identification of mounting surfaces and cartridge cavities across product lines.

OEMs and system integrators - to specify interchangeable valves, slip‑in and screw‑in cartridges, and to simplify procurement/engineering documentation.

Technical documentation, parts catalogs and ordering systems - for clear, standardized coding of valve interfaces.

Quality, testing and maintenance teams - to verify compatibility and trace the defining standard edition for a given cavity or mounting surface.

Using ISO 5783:2019 improves interoperability, reduces engineering errors, and simplifies communication of hydraulic interface specifications.
