Characteristics of Soft Seal Flange Non rising Stem Gate Valve: 1)Flat bottomed valve seat, no accumulation of dirt, making the seal more reliable. 2)The valve disc is wrapped in nitrile rubber as a whole. 3)The valve components are made of corrosion-resistant and stainless steel and copper alloy materials, which can be used in sewage systems to adapt to harsh working environments. 4)Small size, light weight, easy to install and maintain. 5)The valve stem adopts three O-ring seals, greatly reducing friction resistance during switching, and the switch is lightweight and leak free.
10 characteristics of national standard soft seal gate valves: 1)The valve body material should be cast iron, cast steel, stainless steel, and indicate the brand and actual physical and chemical testing data of the cast iron. 2)The material of the valve stem should be stainless steel, and large diameter valves should also have stainless steel embedded valve stems. 3)The nut material is made of cast aluminum brass or cast aluminum bronze, and its hardness and strength are both greater than those of the valve stem. 4)The material of the valve stem liner should have a hardness and strength not greater than that of the valve stem, and should not form electro chemical corrosion with the valve stem and valve body under water immersion conditions. 5)Material of sealing surface. 6)Integral sealing: The valve adopts integral sealing, which has good adhesion and geometric dimensions, ensuring reliable sealing and long service life. 7)Lightweight: The valve is made of ductile iron, which is lightweight and easy to install. |
