2、阀体强度高，安全系数大，能够抗很高的管线应力。
3、阀座采用筒式阀座。
4、阀杆底部设计有止推轴承，防止因阀杆和蝶阀重量而导致的蝶板位移。
5、阀杆采用一节阀杆设计，抗弯强度高，启闭扭矩小。
1.U type flange butterfly valve is based on the large requirements of network design，network type genus of butterfly valve.
2.The body of high strength，high safety factor，can resist high pipeline stress.
3.The cylinder valve seat，valve seat.
4.The stem at the bottom of the design have thrust bearings，prevent the butterfly plate displacement caused by the stem and disc weight.
5.The valve stem by a section of the stem design，high bending strength，opening and closing torque is small.
