Electric flange type hard sealing butterfly valve (ZY type)

 

Electric hard sealing method adopts precise J-shaped elastic sealing ring and triple eccentric multi-layer metal hard sealing structure. , used for regulating flow and truncating flow.

 

 

• The valve adopts triple eccentric sealing structure, the valve seat and disc are almost free of wear, and it has the sealing function of tighter closing.

• The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance, corrosion resistance and long service life regardless of low temperature and high temperature.

• The cover of the butterfly plate is made of surfacing cobalt-based cemented carbide, the sealing surface is wear-resistant and has a long service life.

• The valve has a bidirectional sealing function, and is not restricted by the flow direction of the medium during installation, nor is it affected by the spatial position, and can be installed in any direction.
