PTFE Lined Butterfly Valve
The 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.
