Soft seal butterfly valves refer to the butterfly valves with the soft seal. As the soft seal is made to provide an appreciated sealing, the performance of the soft sealing butterfly valves has been ensured in order to meet the requirements. Similar to other types of the butterfly valves, the butterfly plate of the soft sealing butterfly valve is installed in the direction of the pipe diameter. With the rotation from 0 degree to 90 degree, the effects have been realized.
Generally speaking, the soft seal butterfly valve is used to achieve piping system as an on-off and flow control components. For example, they have been widely used in the fields like the petroleum, chemical industry, metallurgy, water, electricity and many other areas. However, they have some unpleasant factors to influence the applicable fields. And the manufacturing materials for the seals mean a lot. Generally speaking, the materials for the soft seals including the rubber and PTFE lead the soft sealing butterfly valves to be not suitable for working conditions with high temperature and high pressure. And the poor corrosion resistance restricts the applications, either. As a result, some manufacturers have done some improvements to improve the durability, such as the adoption of the multiplied seals for the soft seal butterfly valves.
