Discover the ultimate solution for all your public water system or treatment works needs with our AIS compliant valve offerings. Under the American Iron and Steel (AIS) provision, compliance is essential, particularly for projects funded through the Clean Water State Revolving Fund (CWSRF) and Drinking Water State Revolving Fund (DWSRF). At Cornerstone Valve, with our headquarters in Missouri City, Texas, we are proud to deliver valve products that adhere strictly to AIS standards.

Our collaboration with locally based forge masters and manufacturers ensures the production of various materials and grades, fully meeting AIS compliance. Upon request, we provide a signed AIS letter of certification, specifying the product details and confirming its compliance with the AIS provision. Remember to specify AIS and any other regulatory requirements when requesting a quotation from us. Choose Cornerstone Valve for reliable, high-quality, AIS compliant valve solutions.
