GP-1000 Series reducing valve nominal diameter selected chart
Example (1)
The selected methods of the valve nominal diameter of one time lateral pressure (P1) is 0.6MPa, the secondary side pressure (P2) is 0.4MPa, steam flow rate is 800kg / h are as follows: Find the intersection (A) of one side pressure of 0.6MPa and the secondary lateral pressure of 0.4MPa, from (A) point to draw a vertical line, seeking the intersection (B) of flow 800kg/h, intersection (B) is between nominal diameter 40A and 50A, selecting the large side, 50A is the desired nominal diameter.
example (2)
The selected methods of the valve nominal diameter of one time lateral pressure (P1) is 0.8MPa, the secondary side pressure (P2) is 0.05MPa, steam flow rate is 600kg / h are as follows: find the diagonal intersection(C) with one side pressure is 0.8MPa, seeking intersection (D)of slash and the secondary side pressure of 0.05MPa, from (D) point to draw a vertical line, seeking the intersection (E) of 600kg/h flow, intersection (E) is between nominal diameter 32A and 40A, selecting the large one, 40A is the desired nominal diameter.
