Product introduction:


Middle-line soft seal butterfly valve is the preferred conventional butterfly valve for pipeline. The utility model has the advantages of simple structure, small flow resistance coefficient, near-straight flow characteristics, and is free of debris, in light weight, convenient to be installed, and small in driving torque. This valve can be used to cut off media and also to regulate the flow of media used. Its actuating device can be made according to user's requirements, either in manual, electric, pneumatic, or other forms. Different materials are selected and seal rings of different materials are provided. The valve is applicable to different media and working conditions and makes the cost and performance to achieve the best match. The soft seal butterfly valve is suitable for the temperature lower than 120℃ and nominal pressure lower than 1.6 MPa,and it is suitable for the industries such as water supply and drainage, sewage, food, heating, gas, shipping, hydro-power, metallurgy, energy system, and textile,particularly suitable for two-way seal box valve bodies that are easy to be rusted.

Product features:


1. Compact and portable, easy to remove and maintain, and can be installed at any position;

2. Its flow characteristic tends to be straight line and it is of great regulating performance;

3. Simple structure, compact, small operating torque and fast opening by only rotating 90 degrees;

4. Internal leakage point is eliminated by connecting valve plate with valve rod without pin;

5. The encircle of valve plate is made as ball to improve the sealing performance and prolong the service life of valve, and there is zero leakage after the valve has been opened and closed for 50,000 times under pressure;

6. Sealing element can be replaced, and suitable for two-way seal box.

7. The butterfly disc can be painting as the request.

8. The valve can be flange or the wafer.

9. The motivation can be the handle, pneumatic and electrically operated valve.
