California-based GF Piping Systems has introduced a quick and easy-to-use tool that calculates the correct Pressure Regulating Valve (PRV) size to select from the company’s new line of high purity performance PRVs.
To use the tool, the customer simply enters the valve type desired (either pressure retaining or pressure reducing) along with the process parameters and the program calculates the optimum valve size to select.
The new tool can be accessed from the company’s homepage ‘Downloads & eTools’ and then clicking on ‘Valve Sizing Tool’ from the pull-down menu. Users then select the desired valve type, pipe dimension, pressure range and unit type, and enter in the inlet pressure and flow rate. From there, the program calculates a hysteresis curve and displays the operating point on a graph. Depending on the operating point shown on the graph, the customer then obtains the proper valve size to order.
