WCB lined wafer butterfly valve

WCB wafer lined butterfly valves

Features
1. Centerline WCB wafer lined butterfly valves for the entire board with the valve seat in the 360 degree circle with concentric (center line), sealed with two-way function, pressure, flow can be allowed to adjust freely.

2. The use of patented technology to have lined butterfly valve processing board, plastic and metal fluoride matrix closely with seamless, efficient scheduling to make laminated bubble, since the elimination of layers, cracks and other defects in process.

3. Seat with 360 degree radial sealing force elastic pad back to exert radial force, the automatic adjustment of deformation, a reliable guarantee for long-term use of state media with no leakage.

4. Butterfly board, under the shoulder-axis multi-level flexible sealing load to achieve automatic compensation sealed so that the whole constitutes a shaft seal without gaps vice to ensure that no leakage of media.
