Stainless Steel Butterfly Valves
Series 486
ANSI and Metric Flange Compatible
All stainless steel butterfly valve
The Series 486 inflatable seated butterfly valve from Posi-flate features a fully machined 316L stainless steel housing. The single piece disc and shaft is available in a number of materials including 316L stainless steel and hasloy. The disc may be polished to a mirror finish or coated with PTFE, nylon or other high performance coating.
The stainless steel valve is ideal for powders, granules, slurries and liquids and is available in sizes 2" (50 mm) to 20" (500 mm). Typical applications include loading and unloading of process material, sterile air control, and outlet valves for storage containers or hoppers.
Unique inflatable seat provides better seal, less wear, longer lifes
Posi-flate's unique inflatable seat design provides a better seal by utilizing air pressure to expand the seat against the disc, providing more sealing area and an even pressure distribution against the disc every time. The inflatable seat automatically compensates for wear when it inflates against the disc which extends the valve life considerably.
Torque requirements are substantially lower with the Posi-flate butterfly valve since the disc does not impinge the seat. The smooth profile of the disc provides minimum flow resistance and reduces material build-up.
