Description of GP-1000 Series model code
Nominal Sizes Selection Chart (For Steam)
Example 1
When selecting the nominal size of a pressure reducing valve whose inlet pressure (P1), reduced pressure (P2), and steam flow rate are 0.6 MPa, 0.4 MPa, and 800 kg/h, respectively, first find intersection point (A) of the inlet pressure of 0.6 MPa and the reduced pressure of 0.4 MPa. Trace down vertically from this intersection point to find intersection point (B) with the flow rate of 800 kg/h. Since intersection point (B) lies between nominal sizes 40A and 50A, select the larger one, 50A.
Example 2
When selecting the nominal size of a pressure reducing valve whose inlet pressure (P1), reduced pressure (P2), and steam flow rate are 0.8 MPa, 0.05 MPa, and 600 kg/h, respectively, first find intersection point (C) of the inlet pressure of 0.8 MPa and the diagonal line. Trace down to the left from this intersection point to find intersection point (D) with the reduced pressure of 0.05 MPa. Trace down vertically from intersection point (D) to find intersection point (E) with the flow rate of 600 kg/h. Since intersection point (E) lies between nominal sizes 32A and 40A, select the larger one, 40A. ∙ Set the safety factor at 80 to 90%.
Specifications Selection Chart
Find the intersection point of the inlet and reduced pressures. If the intersection point is within any of the ranges shown in the chart above, the pressures are controllable. ∙ Range (A) and (C): GP-1000 Series except GP-1002 and 1012 ∙ Range (B) and (C): GP-1002 and 1012
Corrected Cv value
Example Take a pressure reducing valve whose inlet pressure is 0.8 MPa, the reduced pressure is 0.05 MPa. Find the inlet and reduced pressure intersection point (A) at the above chart, then draw a horizontal line in the leftward direction to pint (B) which indicates a correction coefficient of 0.85. For a nominal size of 25A, the corrected Cv value would be calculated as follows: 4 (rated Cv value) 0.85 (correction coefficient) = 3.4
