Characteristics

Flat-bottom valve seat: The traditional gate valve often accumulates in the groove of the valve bottom due to foreign matter such as stones, wood blocks, cement, paper scraps, debris, etc. after the water is washed, which is easy to cause the water to close and form a water leakage phenomenon. . The bottom of the soft sealing gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation, so that the fluid is unobstructed.

Integral encapsulation: the valve is made of high-quality rubber for the whole, the outer rubber, the domestic first-class rubber vulcanization technology enables the vulcanized valve to ensure accurate geometrical dimensions, and the rubber and ductile iron valves are then firm, not easy to fall off and elastic memory is good. .

Corrosion resistance: The valve body is coated with powder epoxy to prevent corrosion and rust of the valve body. It can also be used in sewage systems. It is not easy to break. Traditional iron gate valves in the past often cause breakage due to impact, collision or overlap of foreign objects. Since the body is changed to ductile iron, this situation can be greatly reduced.

Three "O" type: Because the valve stem is designed with three "O" ring seals. It can reduce the frictional resistance during switching, greatly reduce the leakage phenomenon and replace the sealing ring without stopping the water.

Helps to drink raw: 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 water or corrosion, which can be used for raw drinks.

Precision cast body: The valve body is precision cast, and the precise geometry allows the valve to be sealed without any finishing in the north of the valve body.

Light weight: The body is made of ductile casting, and the weight is reduced by about 20% to 30% compared with the traditional gate valve, which is convenient for maintenance.
