foreword
This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents"
drafted:
This document is part 2 of GB/T 8100 "Hydraulic Valve Mounting Surface": GB/T 8100 has released the following parts:
--- Part 2: Speed control valve;
--- Part 3: Pressure reducing valves, sequence valves, unloading valves, throttle valves and check valves:
This document replaces GB/T 8098-2003 "Hydraulic Transmission Belt Compensated Flow Control Valve Mounting Surface", which is the same as GB/T 8098-2003
Compared to this, the main technical changes are as follows:
--- Changed normative references (see Chapter 2, Chapter 2 of the:2003 edition);
--- Delete the mounting surface with the main port diameter of 28:4mm (see 6:10, 6:11, 7:10, 7:11, Figure 9, Figure 10, Table:2003
17~Table 20);
--- Changed the graphic symbols of the speed control valve (see Table 2, Table 4, Table 6, Table 8, Table 10, Table 12, Table 14, Table 16);
--- Deleted Appendix A (see Appendix A of the:2003 edition):
This document is modified to adopt ISO 6263:2013 "Hydraulic Transmission Belt Compensated Flow Control Valve Mounting Surface":
The technical differences between this document and ISO 6263:2013 and their reasons are as follows:
--- Regarding normative reference documents, this document has made adjustments with technical differences to adapt to the technical conditions of our country and the circumstances of the adjustment:
The situation is reflected in Chapter 2 "Normative References", and the specific adjustments are as follows:
● Replace ISO 1219-1 (see 4:2) with GB/T 786:1 which is equivalent to adopting international standards;
● Replace ISO 4401 with GB/T 2514 modified to adopt international standards (see Chapter 8);
● Replace ISO 5783 with GB/T 14043 which is equivalent to adopting international standards (see 4:3);
● Replace ISO 5598 with GB/T 17446 which is equivalent to adopting international standards (see Chapter 3);
● Removed ISO 3601-2:2008 (see ISO 6263:2013, Chapters 2 and 5:1):
The following editorial changes have also been made to this document:
--- Modify the installation surface code "6263-×-×-×-13" to "GB/T 8100:2-×-×-×-2021":

Introduction
In a hydraulic transmission system, power is transmitted and controlled by pressurized fluid in a closed circuit: The hydraulic valve is the most typical in the system
A type of element that controls the flow direction, pressure or flow of a fluid in a closed loop:
GB/T 8100 specifies the dimensions of the installation surface of hydraulic valves, which are to be composed of 5 parts:
--- Part 1: Four-port directional valve: The purpose is to determine the size of the installation surface of the four-port directional valve (temporarily GB/T 2514-2008):
--- Part 2: Speed control valve: The purpose is to determine the size of the mounting surface of the speed control valve:
--- Part 3: Pressure reducing valves, sequence valves, unloading valves, throttle valves and check valves: The purpose is to determine the pressure reducing valve, sequence valve, unloading valve, joint
Dimensions of the mounting surface for flow valves and check valves:
--- Part 4: Relief valve: The purpose is to determine the size of the mounting surface of the relief valve (temporarily GB/T 8101-2002):
--- Part 5: Four-port and five-port servo valves: The purpose is to determine the size of the installation surface of the four-port and five-port servo valves (temporarily for
GB/T 17487-1998):
The five parts of GB/T 8100 are formulated by ISO 's independent standards: In order to facilitate the systematic management and implementation of the standards, the independent standards are
The quasi-combination is a sub-section standard:
