Easy-to-Use Calculation Tool

To ensure proper valve performance, 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.

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

The new High Purity Pressure Control Valve family design incorporates a special patent pending piston that eliminates the use of elastomers in the valve, eliminating particle shedding for improved operation. This is important in demanding applications that require only minimal amounts of particles in the flow stream. It also eliminates all exterior metal parts, re-torqueing, and provides easy maintenance. These one-of-a-kind valves can be used in a wide range of markets including water treatment, chemical processing, microelectronics, pharmaceutical, life sciences, and solar.

In addition to its elastomer-free capability, high-purity operation is further enhanced via the valve's threaded bonnet, which has no exposed metal bolts. The central housing nut does away with re-torqueing 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.
