涡轮法兰软密封蝶阀
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.
