Parameter

Double Flange Butterfly Valve ,is a normal type of butterfly valve

Valve body and seat are adopted with split design for easy maintenance and replacement.
After maching 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.
Valve stem and valve body are equipped with 4 oil proof bearing,which is benefical to stem support.the upper shaft hole is equipped with 2 o-ring and 1 special rectangular screw ring water seal,which make s the axial seal more reliable.
The 2 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 to ensure the sealing of valve seat end face and the valve plate.
After quenching and tempring process ,the pin material of butterfly valve has high strength and high corrosion resiatance ,and the connection is more safe and stable.
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.
LT type valve body is thicker than the normal wafer butterfly valve with high pressure resistance and not easy to deform.

Advantage

The butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid control characteristics. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened. When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.
