Product advantages:

1.Bundor patent products, patent certification.

The product side flanges comply with national, German, Russian, American, British and Japanese standards and other domestic and international standards for multiple pressures, easy connection and wide adaptability, which can reduce the type of purchase and stock.

2.The thickness of valve body wall is up to standard.

The valve body wall thickness meets the requirement of GB 26640, the thickness is up to the standard, and the pressure strength is guaranteed.

3.Valve body valve plate is made of QT450-10 material

Valve body valve plate is made of qt450-10 material with spheroidization rate above grade 3, tensile strength of 450Mpa and elongation of >10%.

4.Good sealing and long service life of valve seat

The valve seat is made of imported rubber material, with more than 50% rubber content; Elongation at break greater than 350%, valve sealing reliable, long life.

5.Soft back with wide side seat

Soft backrest wide side valve seat, is advantageous to the valve installation, in the pipeline and flange boss contact surface is wide, sealing performance is reliable. Life is longer than a hard back. And easy to remove and replace.

6.No pin structure to avoid corrosion

Butterfly plate and valve shaft adopt through shaft without pin structure to avoid leakage caused by hole mounting pin and accelerated corrosion caused by coating damage.

7.Valve body is sprayed with Aksu epoxy powder

The valve body is sprayed with world-renowned Aksu epoxy resin powder, which has stronger adhesion and better environmental tolerance after melting and curing.
