First select a size, then the appropriate pressure rating or pressure group. Then select a spring range by clicking on it.  Next, select the orifice size with the appropriate Cv value listed. This will require some computation so as not to oversize or undersize the valve.  Then select the proper material for the body #9 and piston #7 which are the only wetted materials in this valve. Next, select the proper piston seal material #8, which must also be suitable for the media used. The more elastic Buna and Viton & Epdm seals tend to create less of a piston drag than the harder Teflon (PTFE) seal. The softer elastomeric seals produce a much closer band between crack and reseating pressures. Normally viton will handle most solvents, oils and chemicals and can handle most media at a wide range of temperatures.  The temperature limits and capabilities of the elastomers and metal selections are are displayed for each material listed below. Next select the Spring chamber #3, spring hardware #1 & #2. The adjusting spring #5 is normally supplied in a chrome silicon steel which is completely protected inside the spring chamber and is not wetted or exposed to the flow media. These are all isolated (non-wetted) from the fluid media and should be selected based on the external environment the valve is exposed to. The carbon steel spring chamber, when selected, is painted on the exterior and interior to withstand normal atmospheric corrosion. Make sure all the circles are filled in, one for each selection. After the customized selection is made, click to continue and instructions will be provided to either print or e-mail the selection to someone, or  even to yourself, or to proceed with ordering the item on line. Printing the selection will not commit one to ordering the items selected. Don't forget to update the quantity to take advantage of any quantity discounts.
