Corrosion Resistant Industrial Control Valve

The butterfly valve plate of the wafer type butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0°-90°. When the rotation reaches 90°, the valve is fully opened. This valve is generally installed horizontally. The wafer butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics.

Our PTFE Lined Butterfly Valve is a quarter-turn rotary valve that achieves on-off and throttling control of fluid media by rotating the disc 90 degrees. The entire internal wetted surface of the valve—including the valve body, disc, and seat—is fully lined with high-quality PTFE (Polytetrafluoroethylene), a synthetic fluoropolymer renowned for its exceptional chemical inertness, low friction coefficient, and wide temperature adaptability. This full-lining design ensures that no metal components come into direct contact with the process medium, maximizing corrosion protection and preventing medium contamination, while the streamlined disc structure minimizes fluid resistance and improves flow capacity.
