> This image from the 1925 Rensselaer Valve Company 1925 catalog shows two 42” 300 WOG valves loaded on a flatcar for shipment. Rensselaer Valve was located in Troy, New York. They specialized in large diameter iron valves.

This page, from the Powell 1911 Catalog #10, shows a typical steam valve of that era. The lack of bolt holes was common in early valve catalogs, because there was not a common bolt hole standard back then. It was up to each customer to specify the required pattern information.

This odd check valve design was actually used by several manufacturers during the 20’s and 30’s. I guess maintenance was a problem because they were gone from manufacturer’s catalogs by WW II. This is from the Ludlow Valve Company 1925 catalog. Ludlow was based in Troy, New York. Both Ludlow and Rensselaer valves are still manufactured today under the Patterson Pump label.

This ad was also from the Vogt refinery book and features a unique testing set-up and procedure: 3500 psi for 24 hours! That is quite a production test.
