BSRIA has launched an updated version of BSRIA Technical Standard BTS/1 2019 – Test Method for PICVs and DPCVs, which supersedes the original version launched in 2012 and now includes a new dedicated method for testing differential pressure control valves.
The changes made to the PICV testing method within the standard include:
- an updated schematic of the test rig setup.
- introduction of clearly defined test tolerances for all measured parameters.
- implementation of a prescribed stabilisation period prior to each of the performance tests being carried out and a reduction in the number of cycles per test.
The method for performance testing DPCVs is divided into the following two stages:
Fixed Load Tests – this test indicates any inherent hysteresis in the valve differential pressure performance as differential pressure outside the controlled loop rises and falls across the full range of the DPCV.
Variable Load Tests - this test indicates any inherent hysteresis in the valve differential pressure performance as flow rate rises and falls across the full range of the DPCV.
The standard is free to download from the BSRIA website.
Vitor Carneiro, Senior Test Engineer, BSRIA Test, said:
“We are delighted to announce the launch the latest version of BTS1/2019, which is the amalgamation of 7 years testing experience and engagement with key industry stakeholders to deliver a streamlined and more clearly defined set of requirements. We look forward to further supporting industry and working with new and existing clients to deliver robust results to demonstrate product performance”.
