The Vatac fully Fluorine lined butterfly valve is designed
for aggressive chemical and ultra-pure applications. Fluorine lined resists
chemical attack from most known chemical compounds, and with a flexible liner
design utilizing a full width, 360 degree, resilient back up liner offers
bubble tight shut off in even the most demanding installations. Redundant shaft seals provide a tight,
reliable seal to the environment. This is a “maintenance free” valve design
which uses long life sleeve bearings and avoids the use of an adjustable
packing gland.
The valve shall be a 90 turn clockwise to close, non-jamming, resilient seated
valve for zero leakage service. The valve shall be torque seated and designed
in such a manner that the disc can be rotated the seat with out the actuator. Also this valve
enables the fluid perfect shut-off regardless of the flow direction.
