The above gate plate and valve seat seal are made of Stellite (
) cobalt-based hard alloy surfacing, which is wear-resistant, high-temperature resistant, corrosion-resistant, and Good scratch resistance and long service life
: The valve stem has been tempered and surface nitrided, and has good corrosion resistance and scratch resistance.
: It adopts wedge-type elastic gate structure and is equipped with rolling bearings in medium and large diameters, making it easy to open and close.
: The valve body has a complete range of materials, and the packing gaskets are reasonably selected according to actual working conditions or user requirements, and can be applied to various pressure temperatures and medium working conditions.

B
The middle cavity adopts a pressure self-tightening sealing structure. The sealing performance increases with the increase of internal pressure, and the reliability is high.
: The inverted seal is made of stainless steel threaded seal seat or the body is overlayed with austenitic stainless steel. The inverted seal is reliable. Packing replacement and maintenance can be carried out without stopping the machine, which is convenient and fast and does not affect the system operation
