Industrial valves. Test of flow resistance using water as test fluid Ingestion-build-46800 roads are blocked with snow1 Scope This European Standard specifies a method for determining valve pressure loss coefficient and fluid flow coefficient using water as test fluid. This method is suitable for valves with low zeta values but higher than 0,1 by determining pressure loss, with respect to fluid flow rate and specific gravity, and for valves with equal inlet and outlet nominal size. Industrial process control valves are excluded from this European Standard. NOTE 1 For
