The German standard ductile iron elastic seat seal gate valve utilizes the compensating effect of slight deformation generated by the elastic gate plate to achieve good sealing effect. This valve has significant advantages such as light opening and closing, reliable sealing, good elastic memory, and long service life. The German standard ductile iron elastic seat seal gate valve can be widely used as a regulating and shut-off device in fluid pipelines such as tap water, sewage, construction, food, electricity, metallurgy, textile, energy systems, etc.

The characteristics of German standard ductile iron elastic seat seal gate valve:

1、 Flat bottomed valve seat

Traditional gate valves often accumulate in the groove at the bottom of the valve due to external objects such as stones, wooden blocks, cement, paper scraps, debris, etc. after flushing with water. It is easy to cause leakage due to the inability to close tightly. The low part of the soft seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation and ensures unobstructed fluid flow.

2、 The valve body of the German standard ductile iron elastic seat seal gate valve is coated with powder epoxy resin, which can prevent corrosion and rust of the valve body and can be used in sewage systems.

3、 Not easily broken

In the past, traditional cast iron gate valves often suffered from breakage caused by external objects hitting, colliding, or overlapping. Due to the use of ductile iron in this valve, this situation can be significantly reduced.

4、 Three O-ring seals

Due to the use of a three "0" ring sealing design for the valve stem, friction resistance during opening and closing can be reduced, significantly reducing water leakage. Therefore, the sealing ring can be replaced without stopping the water supply during construction.

5、 Helps with drinking

Due to the epoxy resin coating inside the valve body, the inner and outer surfaces of the gate are covered with rubber to prevent rust or corrosion, making it suitable for drinking.

6、 Whole package adhesive

The valve plate is made of rubber for overall internal and external packaging. The domestic rubber vulcanization technology enables the vulcanized valve plate to have geometric dimensions, and the rubber is firmly connected to the ductile iron gate plate, which is not easy to fall off and has good elastic memory.

7、 Lightweight

The German standard ductile iron elastic seat sealing gate valve is made of ductile iron casting, which reduces the weight by about 20% -30% compared to traditional gate valves. Easy installation and maintenance.

8、 Precision cast valve body

The valve body of the German standard ductile iron elastic seat sealing gate valve is cast, and the geometric dimensions of the valve body enable the sealing of the valve without any precision machining inside.
