TECOFI VPE4548-08EP Flanged Butterfly Valve, Ductile Iron Disc, PN16, Gearbox

VPE4548-08EP is a Tecofi (France) flanged butterfly valve of the Teclarge FL 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 DN350–DN1200, maximum working pressure 16 bar, working temperature -15°C / +130°C (peak -30°C / +150°C).

How does VPE4548-08EP differ from VPE4508-08EP?

VPE4548-08EP has a maximum working pressure of 16 bar (PN16 flanges) while VPE4508-08EP is rated 10 bar (PN10). The body / seat test pressure is 24 / 17.6 bar for VPE4548-08EP and 15 / 11 bar for VPE4508-08EP. Body, disc (ductile iron disc), seat (Heat EPDM), handwheel gearbox and working temperature are the same.

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 07/07/2025). 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, VPE4548-08EP is used in water treatment, pumping and irrigation; fluids: cold water, hot water, wastewater, demineralised water, liquid discharges, compressed air, alkalis and sodium hydroxide, etc.
