Delivery

The sealing pair of the soft sealed butterfly valve is made of metal material on one side and elastic non-metallic material on the other side, usually rubber or PTFE plastic. The combination of this sealing material makes the soft sealed butterfly valve have good sealing performance, but it is not resistant to high temperatures, easy to wear, and has a short service life.

The sealing seat of the soft sealed butterfly valve is made of rubber or PTFE plastic, which has excellent sealing performance and can achieve zero leakage. However, its service life is relatively short and it is not resistant to high temperatures. It is also not suitable for some highly corrosive medium pipelines.

The flange type soft seal butterfly valve has the advantages of simple structure, low flow resistance coefficient, linear flow ourphpacteristics, no debris retention, light weight, easy installation, and low driving torque. This type of valve can be used to cut off the medium and also to regulate the flow rate of the medium. By ourphping parts made of different materials and using sealing rings made of different materials, it can adapt to different media and working conditions, achieving the best cost and performance. The flange type soft seal butterfly valve is widely used in industries such as water supply and drainage, sewage, food, heating, gas, ships, hydropower, metallurgy, energy systems, and textiles with temperatures ≤ 120 ℃ and nominal pressures ≤ 1.6MPa. It is particularly suitable for bidirectional sealing and valve body corrosion prone occasions, as a regulating flow and intercepting medium.
