The TTV 20W3080 is a concentric, soft-seated wafer pattern butterfly valve with a Rilsan-coated GJS500-7 ductile iron body and a corrosion-resistant bronze disc. This gearbox-operated version covers 2" (DN50) to 12" (DN300) and is supplied with a manual gearbox and handwheel. The dry shaft design keeps the line media away from the shaft and body.
It is an economical choice for sea water isolation and other corrosive liquids and gases in non-corrosive external environments, and with an NBR Buna seat it is commonly used on natural gas. 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.
