Features:
1. Valve body and seat are adopted with split design for easy maintenance and replacement.
2. After machining of valve body, because of without lining rubber, to avoid the pressure deformation of the lining rubber. Which ensure the accuracy of body symmetry and reduce the torque of butterfly valve.
3. Valve stem and valve body are equipped with 4 oil proof bearings, which is beneficial to stem support. the upper shaft hole is equipped with two O rings and one special rectangular screw ring water seal, which makes the axial seal more reliable.
4. The two ends of the valve plate shaft hole are designed with grooves, which can effectively prevent damage of valve seat caused by the excessive extrusion when valve shaft is loaded into valve the to ensure the sealing of the valve seat end face and the valve plate.
5. After quenching and tempering process, the pin material of butterfly valve has high strength and high corrosion resistance, and the connection is more sate and stable.
6. A non-pin stem adopts an anti-exit structure, spring + type card structure are used in the upper part of the stem, which can not only compensate for installation errors, but also prevent the stem from loosening.
7. LT type valve body is thicker than the normal wafer butterfly valve with high pressure resistance and not easy to deform.
