Soft Seal Gate Valve Series 
The valve stem is designed with three "O" rings. It can reduce the friction resistance when switching, greatly reduce the leakage phenomenon and replace the The inside and outside of the valve body are coated with non-toxic resin, which meets the sanitary conditions, enhances the corrosion resistance and eliminates the secondary pollution to the water quality.
The valve stem nut is embedded in the gate, so that it will not be loose, and is not easy to be corroded, so that the service life is long.
The bottom of the valve is flat, not easy to accumulate debris, the fluid is unobstructed, and the switch is free.
The ram surface is wrapped with EPDM. Reliable sealing, anti-wear and zero leakage rate.sealing ring

About Three Cast Iron
a.Malleable Cast Iron(MOS Iron/ Magang) 
b.Ductile Cast Iron 
c.Gray Cast Iron 
Compared with Gray cast iron, Ductile iron in intensity has an absolute advantage. The tensile strength of ductile iron is 60k, while the tensile strength of Gray cast iron is only 31k.The yield strength of ductile iron is 40k,while Gray cast iron did non yield strength. The strenght and cost of ductile cast iron is much superior the Gray cast iron.Ductile cast iron and Grey Cast Iron in the corrosion resistance is in the same.    
Ductile cast iron has the same strength of cast steel, but also has excellent corrosion resistance, and the cost of ductile cast iron is lower than cast steel.
