Operating temperature of triple eccentric butterfly valve

The triple eccentric butterfly valve is suitable for many places, and its material selection is very large, and it can also cope with high and low temperature and various corrosive media such as acids and alkalis. Especially in the aspect of large diameter, with its zero leakage advantage, it is constantly replacing the bulky gate valve and ball valve on the globe valve; similarly, with its advantages of regulating function, it is also replacing the bulky globe valve on the regulating valve. valve. Then in this article, the editor of Bundor Valve will give a introduction to this.
There are three common triple eccentric butterfly valve models: D343F, D343H, D343W. After installation on the pipeline, the valve body and the sealing surface are in direct contact with the medium of the triple eccentric butterfly valve, so the material of the sealing surface also determines the operating temperature of the triple eccentric butterfly valve.
The operating temperature range of the triple eccentric butterfly valve model D343F: 0℃-150℃;
Model D343H and D343W triple eccentric butterfly valve operating temperature range: -29℃-425℃.

Features of triple eccentric butterfly valve:
1 The triple eccentric butterfly valve usually adopts metal hard sealing valve seat, which solves the problem of high temperature resistance. A multi-layer sealing ring made of stainless steel sheets and graphite sheets is interleaved and laminated around the butterfly disc. This seal has the dual advantages of metal hard sealing and elastic soft sealing, which solves the leakage problem.
2 The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance, corrosion resistance and long service life no matter in the case of low temperature and high temperature.
3 The sealing surface of the butterfly disc is made of surfacing cobalt-based hard alloy, and the sealing surface is wear-resistant and has a long service life.
4 The large size butterfly disc adopts truss structure, which has high strength, large flow area and small flow resistance.
5 According to user needs, the hard-sealed butterfly valve can be designed to have a two-way sealing function, which is not restricted by the flow direction of the medium during installation, and is not affected by the spatial position, and can be installed in any direction.
6 The drive device can be installed in multiple positions (rotating 90° or 180°), which is convenient for users to use.
