Pressure Reducing Calculator - For Model 500XL , NR3XL ,600XL



Step Reduction :-
1) Start by entering the values for inlet and outlet pressure. The Reduction Ratio value determines the overall value of reduction. (To prevent valve chatter and unecessary wear, a ratio of 4:1 or less is desired for every valve used.)
2) The program will now determine if a step reduction is needed.
3) If step reduction is needed, listed will be the amount of valves (steps) needed as well as the value to set the valves at to ensure proper function.
*Note: High Range/Low Range valves may be suggested and are an optional addition to valves.





Low Flow :-
1) Start by entering the values for maximum flow rate and minimum flow rate.
2) Select a valve size.
*Note: This program might suggest a larger valve size due to the conditions of the flow values entered.
3) Valves shown with "Supplied in Size" are valves that are manufactured in that selected size. To explore options further, click valve name (or the tabs located at the bottom) and create a model based on the flow characteristics. To access the valves' specification sheet, click the cell labeled "SpecSheet"

For Model 500XL :-
This program will create a system containing the 500XL specifying the amount of valves, pressure settings, and flow characteristics for proper function.
1) Enter the value for the max flow through the system. Then, enter the value for the minimum flow. (If the minimum flow is unknown, leave blank or enter "0"
2) Enter the value for the allowable falloff. Falloff is defined as the pressure drop within a system due to a given flow: i.e. the greater the flow the greater the falloff. *Note: Falloff is typically acceptable in the range of 12-17(PSI)
3) Enter the value for the system's inlet pressure and the desired outlet pressure.
4) The program will now generate a table with values relevant to the system's characteristics.
5)Please refer to the cell "Figure. Number" in order to see a visual representation of the system.
*Note: figure is only a representation of the system and may vary in detail from each application.


Model NR3XL :-
This program will create a system containing the NR3XL specifying the amount of valves, pressure settings, and flow characteristics for proper function.
1) Enter the value for the max flow through the system. Then, enter the value for the minimum flow. (If the minimum flow is unknown, leave blank or enter "0"
2) Enter the value for the allowable falloff. Falloff is defined as the pressure drop within a system due to a given flow: i.e. the greater the flow the greater the falloff. *Note: Falloff is typically acceptable in the range of 12-17(PSI)
3) Enter the value for the system's inlet pressure and the desired outlet pressure.
4) The program will now generate a table with values relevant to the system's characteristics.
5)Please refer to the cell "Figure. Number" in order to see a visual representation of the system.
*Note: figure is only a representation of the system and may vary in detail from each application.





Model 600XL :-
This program will create a system containing the 600XL specifying the amount of valves, pressure settings, and flow characteristics for proper function.
1) Enter the value for the max flow through the system. Then, enter the value for the minimum flow. (If the minimum flow is unknown, leave blank or enter "0"
2) Enter the value for the allowable falloff. Falloff is defined as the pressure drop within a system due to a given flow: i.e. the greater the flow the greater the falloff. *Note: Falloff is typically acceptable in the range of 12-17(PSI)
3) Enter the value for the system's inlet pressure and the desired outlet pressure.
4) The program will now generate a table with values relevant to the system's characteristics.
5)Please refer to the cell "Figure. Number" in order to see a visual representation of the system.
*Note: figure is only a representation of the system and may vary in detail from each application.
