China Soft Sealed Butterfly Valve: Applicable Conditions and Performance Analysis

1. Applicable Conditions

1. Water Treatment Industry

• Soft-sealed butterfly valves are widely used in the water treatment industry and are suitable for switching and regulating media such as water plants and sewage treatment plants. Its good sealing performance can effectively prevent media leakage and ensure water quality safety.
• In the water treatment process, soft-sealed butterfly valves can adapt to different pressure and temperature conditions to ensure the stable operation of the system.

2. Chemical Industry

• The media in the chemical industry are often corrosive, and the material and sealing performance of the valves are extremely high. Soft-sealed butterfly valves are made of corrosion-resistant stainless steel or alloy materials, and are equipped with chemical-resistant rubber or fluoroplastic seals, which can effectively resist the erosion of corrosive media such as acids, alkalis, and salts.
• In addition, the soft-sealed butterfly valve also has good wear resistance and high temperature resistance, and can work stably for a long time under harsh working conditions.

3. Food and beverage industry

• In the food and beverage industry, the requirements for hygiene standards are extremely strict. The soft-sealed butterfly valve uses non-toxic and odorless rubber or fluoroplastic as sealing materials to ensure that the medium will not be contaminated.
• At the same time, the soft-sealed butterfly valve has a simple structure and is easy to clean, which meets the hygiene requirements of the food and beverage industry.

4. Power industry

• The working environment of the power industry is complex and changeable, and the reliability and safety requirements of the valve are extremely high. The soft-sealed butterfly valve adopts advanced manufacturing technology and a strict quality control system to ensure that the quality and performance of the product are stable and reliable.
• In the power system, the soft-sealed butterfly valve can accurately adjust the flow and pressure of the medium to meet the safe operation requirements of the system.

1. II. Performance analysis

1. Sealing performance

• The soft-sealed butterfly valve adopts a multi-layer soft and hard stacked sealing ring design, which not only improves the reliability of the seal, but also extends the service life of the seal.
• The selection of sealing materials is crucial. We select suitable rubber or fluoroplastic materials such as nitrile rubber, EPDM rubber, polytetrafluoroethylene, etc. according to different working conditions to ensure the best sealing effect.

2. Corrosion resistance

• For corrosive environments such as chemical industry, soft-sealed butterfly valves are made of corrosion-resistant stainless steel or alloy materials, and are equipped with chemically resistant rubber or fluoroplastic seals. These materials can effectively resist the erosion of corrosive media such as acids, alkalis, and salts, ensuring the long-term service life of the valve.

3. Wear resistance

• The sealing surface of the soft-sealed butterfly valve has less mechanical wear and is suitable for occasions of frequent opening and closing. At the same time, we also use special wear-resistant materials and surface treatment technology to further improve the wear resistance of the valve.

4. Operational flexibility

• The soft-sealed butterfly valve has a small operating force and switches quickly and smoothly. This is due to its compact design structure and high-quality pneumatic actuators (if needed). In addition, we also provide a variety of operating methods such as manual and electric for users to choose from.

5. Easy maintenance

• The soft-sealed butterfly valve has a simple and compact structure, which is easy to install and maintain. At the same time, we also provide detailed installation guides and after-sales service support to ensure that users can easily complete the installation and commissioning of the valve.

In summary, soft-sealed butterfly valves have been widely used in water treatment, chemical industry, food and beverage, electricity and other industries due to their excellent applicable working conditions and performance characteristics. We will continue to uphold the principle of "quality first, customer first", continuously innovate and improve products and technologies, and provide users with better quality valve products and services.
