The FLOWTEF® ball check valves are made by carbon steel body lined with virgin PFA. Valves are available from DN 15 / ½ ” to DN 200 / 8″, face to face dimension and flanges according to UNI EN or ANSI standard. Depending on the application, the valve can be equipped with full, hollow or ballasted PTFE ball. The PTFE ensures the same PFA lining properties. The valves can be equipped with EPDM, FPM or FFKM O-rings allowing effective seal with gas. The interior design of the valve provides a smooth convey of the fluid with minimal pressure drop. If working conditions and the fluid type allow the right working of the valve, in addition to the classical vertical installation, the valve can also be installed horizontally.
Available with antistatic PFA, PVDF or PP on request.
