Product design 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 safe and stable..

6. A non-pin stem adopts an anti-exit structure, spring +U 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.
