PRV sizing tool
Functionality
This tool allows us to find the dimensions for the pressure regulating valves (PVR).
Selection of the correct valve dimension is important to ensure the optimum design of the piping system. This calculation tool helps you select the correct size pressure control valve for your application.
How does it work?
First, select the valve type, pipe diameter, pressure range, and the desired unit (metric or imperial) of the valve data.
Next, enter the desired pressure (P1 or P2) and flow rate Q as control variables.The calculation tool will then display the hysteresis curve for the valve in the selected dimension. The point on the curve that represents the work point created taking into account specified parameters.
Use the slider under the curve to adjust the dimension of the valve and you will immediately find the result displayed on the curve.
If the duty point is in the yellow range, you should set a minor dimension for your valve on the slider under the curve.
If the graph does not show a duty point, check that the selected flow is within the maximum flow of the selected valve and that the pressure matches the pressure range selection.
