The main advantage of the double eccentric soft sealing flange
FX-D342X-6/10/160 soft sealing flange butterfly valve has two-way sealing performance, the medium can flow in both forward and reverse directions.
The butterfly valve adopts a double eccentric sealing structure, which has the function of closing and tightening when closing, and the sealing performance is reliable.
After opening, ensure that the sealing surface is completely out of contact to ensure that the sealing surface is not damaged.
The sealing surface of the butterfly plate is made of stainless steel, and the sealing surface of the valve body is made of rubber, which has a long service life.
The valve shaft adopts a half-shaft structure, and the butterfly plate adopts a truss structure, which has high strength, large flow area, small flow resistance and energy saving.
The transmission method is driven by a wheel and worm.
The operation of the driving device should be convenient, flexible, safe and reliable.
All internal fasteners of the butterfly valve adopt a reliable anti-loose design mechanism: anti-vibration, anti-loose, and will never loose or fall off.
The shaft system of the butterfly valve adopts a fully enclosed design: to ensure that the butterfly valve opens and closes flexibly and does not get stuck.
The double structure is simple, the volume is small and the weight is light.
The medium and large diameter double eccentric soft sealing flange pipe network butterfly valve has a large effective flow area when fully opened, and it can be opened and closed quickly and effortlessly.
The opening and closing of the disc can be completed by rotating 90 degrees.
The force of the butterfly wrench media is close to the same, but the torque generated is opposite, so the opening and closing torque is small, and good sealing can be achieved under low pressure.
The sealing materials of the double eccentric soft sealing flange pipe network include nitrile rubber and fluorine rubber.
The edible rubber is lined with tetrafluoroethylene so that it has good sealing performance and has excellent sealing performance under any circumstances (up to zero leakage).
The installation method is flexible, and the horizontal or vertical installation can be adjusted at any time according to the installation conditions.
FX-D342X-6/10/160 soft sealing flange butterfly valve can be widely used in the industrial process automatic control system of food, environmental protection, light industry, petroleum, chemical industry, teaching equipment, papermaking, electric power and other industries.
