1 Flat bottom seat
The traditional gate valve is often in the water after washing the pipe because of external objects such as stones, wood blocks, cement, paper scraps, sundries and other silt accumulated in the bottom of the valve groove, easy to cause can not close close and form water leakage phenomenon. The bottom of the soft seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris silting and make the fluid unobstructed.
2 Whole package
The valve uses high-quality rubber for the whole inside, outsourcing glue, domestic first-class rubber vulcanization technology makes vulcanized valve can ensure accurate geometry, and rubber and ductile iron valve then firm, not easy to fall off and elastic memory is good.
3 corrosion
The valve body is coated with powder epoxy resin to prevent corrosion and rust. And can be used in sewage systems. In the past, the traditional cast iron gate valves were often broken due to the impact, collision or overlap of external objects. Due to the use of nodular cast iron, this situation has been greatly reduced.
4 three "O" type
Because the valve stem uses three "O" type ring seal ring design. Can reduce the friction resistance when the switch, greatly reduce the phenomenon of water leakage and can not stop the construction of replacement seal ring.
5 helps to drink raw
As the valve body is coated with non-toxic epoxy resin, the internal and external surfaces of the gate valve are completely covered with rubber to prevent rust or corrosion.
6 Cast valve body
The valve body is precision cast and the precise geometry ensures the valve sealing without any finishing in the north of the valve body.
7 light weight
The body is made of ductile casting, the weight is reduced by about 20% to 30% compared with the traditional gate valve, convenient for maintenance.
