GB/T 20081.1-2021Pneumatic fluid power - Compressed air pressure regulators and filter-regulators - Part 1: Main characteristics to be included in literature from suppliers and product-marking requirements (English PDF)

1 Scope

This document specifies the main characteristics and product identification requirements of pressure reducing valves and filter pressure reducing valves contained in commercial documents.

This document applies to the following pressure reducing valves and filter pressure reducing valves.

---Manually controlled direct-acting type (with or without overflow device);

---Manually control the internal pilot type (such as. nozzle baffle);

---External pilot type.

This document applies to pressure reducing valves whose rated inlet pressure does not exceed 2.5 MPa and outlet regulating pressure does not exceed 1.6 MPa, and applies to

A filter pressure reducing valve whose rated inlet and outlet regulating pressure does not exceed 1.6 MPa and is decontaminated by mechanical methods.

The rated pressure should comply with the recommended pressure selection specified in GB/T 2346.

Note 1.1bar=0.1MPa=105Pa; 1MPa=1N/mm2.

The rated pressure should be selected from the preferred pressures listed in ISO 2944.

Note 2.The main characteristics related to electric-pneumatic pressure control valves in commercial documents are specified in ISO 10094-1.
