GB/T 20081.2-2021 (English Version) PDF

Scope: This document stipulates the test items, test procedures and test results expression methods for testing according to the main characteristics of GB/T20081.1 pneumatic pressure reducing valves and filter pressure reducing valves that should be included in the business documents. The purpose of this document is to: ——Standardize the test procedures and test results presentation methods, so that the performance comparison between different pressure reducing valves and filter pressure reducing valves is simple and clear; Reasonable application of pressure relief valve and filter relief valve. The test items specified in this document are for comparison between different pneumatic pressure reducing valves and filter pressure reducing valves, not for production inspection of each manufactured pneumatic pressure reducing valve and filter pressure reducing valve. Note 1: The related tests of electro-pneumatic pressure control valves are stipulated in ISO10094-2.
