Resilient Seated Butterfly Valve

Taking disc as the closure member, the rubber/PTFE/alloy lined butterfly valve is a kind of product which completes the opening and closing of the pipeline through the rotation of the disc around the valve shaft.

This product is consisted of valve body, valve disc and soft sealed valve seat. Capable of cutting off the fluid, the midline butterfly valve is generally used for the mediums like water, oil, gas and other corrosive product with the temperature less than 80℃.

Features
1. The valve body of the wafer butterfly valve is symmetric by the center line. So, the installation of the PTFE, NBR lined butterfly valve is easy and convenient.
2. Producing with PTFE,NBR, or other materials, the valve seat will not fall off. Besides convenient replacement, the manual wafer rubber lined butterfly valve has good leakproofness and stretch resistance.
3. With integrated structure, the valve stem of the rubber/PTFE/alloy lined butterfly valve has higher strength. The elaborate processing can prevent the medium from leaking effectively.
4. The precise valve disc is polished. Well matched with the valve seat, the valve disc has outstanding sealing performance.
