TECOFI VPG4449-08 Wafer Butterfly Valve, Stainless Steel Disc, Gearbox

VPG4449-08 is a Tecofi (France) wafer butterfly valve of the Tecfly VPG Genius range: ductile iron EN-GJS-400-15 (GGG40) body, 316 stainless steel disc (CF8M), EPDM ACS seat, operated by a gearbox with a cast iron handwheel. Size range DN32/40–DN300, maximum working pressure 16 bar, working temperature -20°C / +130°C.

How does VPG4449-08 differ from VPG4449-02?

VPG4449-08 differs from VPG4449-02 in the operator: VPG4449-08 uses a gearbox with a cast iron handwheel, while VPG4449-02 uses a one-piece aluminium handle, padlockable, with a notched sector giving 10 positions. Body, disc, seat, size range (DN32/40–DN300), maximum working pressure of 16 bar and working temperature are the same for both codes per the Tecofi datasheet. VPG4449-08 weighs 5.48–37.78 kg depending on size, against 1.56–30.5 kg for VPG4449-02.

How to read the VPG code (from Tecofi’s VPG range): 44 = wafer, 49 = 316 stainless steel disc; suffix -02 = handle, -08 = gearbox.

Dimensions and weight by DN

The table is taken from the Tecofi datasheet (version dated 12/09/2024). L is the length between the two flanges (face to face); weight is the valve weight per the datasheet.

Order codes take the form VPG4449-08EP + a four-digit DN (for example VPG4449-08EP0100, VPG4449-08EP0200); ask CAD to confirm the exact code for your size.

Applications

Per the Tecofi datasheet, VPG4449-08 is used in water supply, water treatment, pumping, irrigation and industry; fluids: cold water, hot water, drinking water, air (6 bar maximum for compressed air) and compatible fluids, etc. The datasheet strongly discourages use on steam.
