GB/T 20081.2-2021Pneumatic fluid power - Compressed air pressure regulators and filter-regulators - Part 2: Test methods to determine the main characteristics to be included in literature from suppliers (English PDF)

1 Scope

This document stipulates that the main characteristics of GB/T 20081.1 pneumatic pressure reducing valve and filter pressure reducing valve shall be included in the commercial documents to be tested.

The test items, test procedures and the presentation method of test results.

The purpose of this document is.

---Standardize the test procedures and test results presentation method, so as to simplify the performance comparison between different pressure reducing valves and filter pressure reducing valves

Simple and clear;

---Contribute to the reasonable application of pressure reducing valves and filter pressure reducing valves in pneumatic systems.

The test items specified in this document are for comparison between different pneumatic pressure reducing valves and filter pressure reducing valves, not for each piece of manufacturing

Both the pneumatic pressure reducing valve and the filtering pressure reducing valve have been inspected for production.

Note 1.The electrical-pneumatic pressure control valve related tests are specified in ISO 10094-2.

Note 2.Another dynamic test method for testing the flow rate is specified in ISO 6953-3.This method uses isothermal gas tanks instead of flow meters. This method is only applicable to normal

To test the decreasing part of the hysteresis curve of the flow and overflow flow characteristics.
