• Industrial valves - Test of flow resistance using water as test fluid

  Description:

  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.
