SwRI performs flow coefficient (Cv) testing on a variety of products with either water or nitrogen.

A variety of tests for determining the flow capacity of valves and other flow-limiting devices is provided by Southwest Research Institute (SwRI). Both incompressible and compressible test media are available.

Flow Coefficient (Cv)Testing Procedures

Testing generally follows the procedure outlined in ANSI S75.02, though custom test procedures can be accommodated. SwRI can also provide custom-built test spools in order to meet the specification requirements.

Flow coefficient (Cv) testing can be performed with water or nitrogen. For water tests, flows in excess of 3,000 gpm are available. SwRI has extensive experience with the selection of proper flow and pressure instrumentation required for each test. Nitrogen tests are conducted at the Gas Blowdown Facility.
