TECOFI VPE4408-08EP Wafer Butterfly Valve, Ductile Iron Disc, PN10, Gearbox

VPE4408-08EP is a Tecofi (France) wafer butterfly valve of the Teclarge VPE range: ductile iron EN-GJS-400-15 (GGG40) body, ductile iron EN-GJS-400-15 (GGG40) disc, Heat EPDM seat, operated by a handwheel gearbox whose ISO 5210 output plate takes multiturn electric actuators. Size range DN700–DN1200, maximum working pressure 10 bar, working temperature -15°C / +130°C (peak -30°C / +150°C).

How does VPE4408-08EP differ from VPE4448-08EP?

VPE4408-08EP has a maximum working pressure of 10 bar (PN10 flanges) while VPE4448-08EP is rated 16 bar (PN16). The body / seat test pressure is 15 / 11 bar for VPE4408-08EP and 24 / 17.6 bar for VPE4448-08EP. Body, disc (ductile iron disc), seat (Heat EPDM), handwheel gearbox and working temperature are the same. Size range: DN700–DN1200 for VPE4408-08EP versus DN350–DN1200 for VPE4448-08EP. Note: the January 2026 VPE4408-08 datasheet only covers DN700–DN1200; DN350–DN600 appeared in the older (2020) datasheet. For sizes below DN700 please ask CAD to confirm the right code.

How to read the VPE code (inferred from Tecofi’s datasheets): 44 = wafer, 45 = flanged, 46 = lug; last two digits 08 / 09 = PN10 with ductile iron / stainless disc, 48 / 49 = PN16 with ductile iron / stainless disc; -08 = handwheel gearbox; EP = EPDM seat.

Dimensions and weight by DN

The table is taken from the Tecofi datasheet (version dated 07/01/2026). L is the length between the two flanges (face to face); weight is the valve weight per the datasheet.

The Ref. columns are the per-size order codes in the Tecofi code table CAD holds; an empty cell means that code is not in the table we have, so ask CAD to confirm. If you need another seat material (for example NBR or FPM), say so in your request and CAD will check it with the manufacturer.

Applications

Per the Tecofi datasheet, VPE4408-08EP is used in water treatment, pumping and irrigation; fluids: cold water, hot water, wastewater, liquid discharges, alkalis and sodium hydroxide, etc.
