Tool Calculates Pressure Regulating Valve Size

Dec. 16, 2015
GF Piping Systems introduces a tool that calculates the correct PRV size.

GF Piping Systems introduces a 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, a 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.

"Selecting the proper PRV size is critical to optimal valve performance," explains Jeff Sixsmith, product manager for valves and actuation for GF Piping Systems. "Correct valve size also prevents potential valve damage. Since the ideal PRV size can be different from the piping system size segment it is installed in, size selection may not be obvious."

Customers can access the tool from the company's home page. Users 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.

The new High Purity Pressure Control Valve family design incorporates a piston that eliminates the use of elastomers in the valve, eliminating particle shedding. It also eliminates all exterior metal parts, re-torqueing, and provides easy maintenance. The valves can be used in applications including water treatment, chemical processing, microelectronics, pharmaceutical, life sciences and solar. The valve's threaded bonnet has no exposed metal bolts. The central housing nut does away with retorqueing for easier operation and compact design enables installation in limited space. The modular system allows the user to easily adjust the set pressure range and quickly go from reducing to retaining (or vice versa) by simply switching the cartridge.
