BTV2000 Long Pattern Wafer Style Butterfly Valve

The long pattern BTV2000 butterfly valve is an enhancement to the original design with the valve body thickness increased. This is to allow the valve disc to open unhindered into the adjoining pipeline. This is generally required when the pipework has heavy duty thick wall linings which reduce the bore of the piping and the room available for the disc to rotate into. In the past this problem has been overcome by fitting PTFE spacers with an oversized bore, however having 3 wafer pattern items bolted together in one joint is never ideal. Flowserve has produced a complete range of new castings with the thicker bodies to alleviate this problem, of course all of the standard valves features and advantages are incorporated in this wider bodied valve. The PFA lined disc along with the PTFE lined body – machined from one solid billet of PTFE, are to provide long trouble free performance in highly corrosive processes.
