Product advantages:
1. The sealing surface of the valve seat and valve disc adopts a conical sealing form, which has high wedge force and good sealing effect. The sealing surface is welded with cobalt based hard alloy, which has high hardness, corrosion resistance, wear resistance, abrasion resistance, and extends the service life.
2. Triple sealing, bellows sealing, protective packing sealing, and fully open valve stem cone sealing ensure zero leakage, and permanent packing does not need to be replaced.
3. Double or multi-layer stainless steel Material bellows have good elastic deformation and can be opened and closed for 10000 times.
4. Unique integrated component of bellows and valve disc, bellows and valve disc. The upper pressure plate of the bellows is welded by argon arc welding, which is firm and reliable. At the same time, the medium in the middle chamber is completely separated from the valve stem, protecting the packing and valve stem.
5. The valve stem passes through the inner hole in the middle of the corrugated pipe, and the corrugated pipe is separated from the valve stem, effectively preventing common faults such as corrugated pipe breakage caused by excessive switching or corrugated pipe perforation caused by welding defects.
6. The reverse seal is made by connecting the sealing seat with threads or welding austenitic stainless steel on the body, ensuring reliable sealing. The replacement of the packing can be carried out without stopping the machine, which is convenient and fast, and does not affect the operation of the system.
