GB/T 20081.1-2021 (English Version) PDF

Scope: This document specifies the main characteristics and product marking requirements for regulators and filter regulators included 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 controlled 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 not exceeding 1.6 MPa, and applies to filter reducing valves whose rated inlet and outlet regulating pressures do not exceed 1.0 and are mechanically decontaminated. The rated pressure of 6 MPa should be selected according to the recommended pressure specified in GB/T2346. Note 1: 1ba r=0.1 MPa=105 Pa; 1 MPa=1N/mm2. The rated pressure should be selected from the preferred pressures listed in ISO2944. Note 2: The main characteristics related to electro-pneumatic pressure control valves in business documents are specified in ISO 10094-1.
