6 Scope of application of the jack and identification and marking of the valve function
6.1 Overview
This document provides the construction and dimensions of jacks applicable to cartridge valves with different functions (directional; pull-away valves, pressure control valves, check valves, etc.). Cartridge valves are interchangeable.
6.2 Applicable jacks
The construction and dimensions of the jacks given in this document take into account the interchangeability between the majority of cartridge valves available at the time of publication. Warning; jacks may be fitted with cartridge valves of different functions to prevent mis-fitting.
6.3 Identification and marking of valve functions
Cartridge valves installed in the socket of the oil circuit block in accordance with this document are identified by their function according to ISO 9461 and marked on the oil circuit block in accordance with ISO 16874, see Appendix A.
7 Marking instructions
When choosing to comply with this document, it is appropriate to use the following statement in test reports, catalogues and product sales documents: "The socket of the hydraulic threaded cartridge valve conforms to the provisions of GB/Z41983-2022 "Dimensions of the mounting connection of the hydraulic threaded cartridge valve".
