Concealed stem soft seal gate valve

1 Flat-bottomed valve seat: Traditional gate valves often accumulate in the groove of the valve bottom due to foreign objects such as stones, wood blocks, cement, paper scraps, debris, and other silt after the pipe is flushed with water, which can easily cause leakage due to inability to close tightly. Phenomenon. The bottom of the soft-sealed gate valve adopts the same flat-bottom design as the water pipe, which does not easily cause debris accumulation and allows the fluid to flow unimpeded.
2 Overall rubber coating: The valve is made of high-quality rubber for the entire inner and outer rubber. The domestic first-class rubber vulcanization technology enables the vulcanized valve to ensure precise geometric dimensions, and the rubber and ductile iron valve are firmly connected do not easily fall off, and have elastic memory. good.
3 Corrosion resistance: The valve body is coated with powder epoxy resin to prevent corrosion and rust of the valve body. And can be used in sewage systems. Not easy to break. In the past, traditional cast iron gate valves were often broken due to being hit, collided, or overlapped by foreign objects. This situation can be greatly reduced since the main body is made of ductile iron.
4 Three “O” type: Because the valve stem adopts a three “O” type ring seal design. It can reduce the frictional resistance when switching on and off, greatly reduce water leakage, and replace the sealing ring without stopping water.
5. Conducive to raw drinking: Since the inside of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the gate valve are completely covered with rubber without rust or corrosion, and can be used for raw drinking.
6. Precision cast valve body: The valve body is precision cast. The precise geometric dimensions ensure the sealing of the valve without any finishing work on the northern part of the valve body.
7. Lightweight: The body is made of ductile graphite casting, which is about 20 to 30 percent lighter than traditional gate valves, making it easy to maintain.
