Part I: General Introduction
The bottom of the DIN F4 soft seal gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation and allows the fluid to flow unimpeded.
DIN F4 ductile iron elastic seated gate valve has significant advantages such as light switch, reliable sealing, good elastic memory and long service life.
DIN F4 ductile iron soft seal gate valve can be widely used as a regulating and intercepting device in fluid pipelines such as tap water, sewage, construction, food, electricity, medicine, metallurgy, textiles, and energy systems.

Part III: Production Process
Casting – sand cleaning – machining – spraying – assembling -Test pressure -Storage, the checks at all levels achieve precision work and good quality.

Part IV: Parts Materials
1. Ductile iron valve body.
Ductile iron has the advantages of high strength, good toughness, wear resistance, vibration damping and so on. Production costs are relatively low, which is conducive to reducing the manufacturing cost of the valve. Good processing performance, easy to manufacture complex valve structure.

- 2.Ductile iron+EPDM valve disc.
The valve disc is entirely covered with EPDM rubber, and the rubber is firmly connected to the ductile iron gate plate, not easy to fall off and has good elastic memory, thus ensuring stable valve sealing performance.

Part V: Valve Applications
1. Municipal water supply system:
In the municipal water supply system, soft-sealed gate valves play a vital role. Since the water supply pipeline is usually under high pressure for a long time, the sealing performance of the valve is very high.
2. Petroleum and chemical industry:
In the production process of petroleum and chemical industry, soft-sealed gate valves can be used to adjust and cut off various corrosive media to ensure the safety and stability of the production process. Soft-sealed gate valves can effectively isolate the invasion of external impurities and microorganisms, protect the purity of internal media, and prevent resource waste and safety accidents caused by leakage.
3. Power industry:
Especially in the main steam pipelines and heat network main lines of nuclear power plants and thermal power plants, these equipment need to withstand extremely high pressures and temperatures. Soft-sealed gate valves can still maintain a stable operating state under these extreme environments, effectively cut off or adjust the on-off of the pipeline, and ensure the efficient and safe operation of the entire system.
