Butterfly Valves

The Durco BTV2000 range of PFA / PTFE lined butterfly valves are very robust to provide long trouble free operation. The valves are manufactured by Flowserve who were the first company to introduce fluoropolymer lined butterfly valves to our customers. The body liner is manufactured from a solid billet of PTFE which is machined to shape. All wetted parts are PTFE / PFA offering outstanding corrosion resistance suitable for use for example with sulphuric or hydrochloric acids. The valve is available with a wafer pattern body, a lugged body with threaded bolt holes and a long pattern body to prevent disc fouling on heavy wall lined piping.
