Installation Instructions Extractor Valve Bodies Models 310, 311, 330, 331 & 340 Extractor valve bodies are designed to thread into a female bung on a tank. This thread joint is tapered pipe. It is very important that the installer select a suitable pipe thread sealant for the application. Prior to installing, inspect the valve body and tank bung threads for contamination, thread damage or rust. Remove all contamination & rust, dress any damaged threads. Apply the pipe sealant to the valve body male threads and install to tank. Torque threads to a minimum of 60 ft. lbs. then align body to piping arrangement by continuing to thread body in. Use this procedure to connect threaded connections brought to the valve body. Air test all threaded connections for leaks. Leak testing can be accomplished by installing pipe caps or plugs at the ends of all piping runs. Use test plug, part #391-201-01, if piping pressure tests exceeds the storage tank maximum allowable test pressure. ©2005 EBW F-6310 Rev. 1
