The TTV 40W4040 is a concentric, soft-seated wafer pattern butterfly valve with a CF8M (316) stainless steel body and disc. This gearbox-operated version covers sizes from 2" (DN50) to 24" (DN600) and is supplied with a manual gearbox and handwheel. All units come with 3.1 material certification at no extra cost.
Stainless steel gives much longer life than coated ductile or cast iron where the valve is exposed to harsh environments or aggressive media. It is widely used in the chemical, offshore and process industries. Choose from EPDM, High Temperature EPDM, NBR Buna, Viton, Silicone, Food Silicone or High Temperature Silicone seats, with PN10, PN16 or ANSI 150 flanges. For lever operation in sizes up to 8", see the lever-operated version.
