1. The valve cover of the low temperature butterfly valve is designed with a long neck structure, which can isolate the influence of the cryogenic medium on the filler.

2. Low temperature butterfly valve adopts double eccentric or triple eccentric sealing structure, the seat and butterfly plate almost have no wear and tear, with the sealing function of tighter and tighter.

3. Butterfly plate sealing surface is made of cobalt base cemented carbide, the sealing surface is wear resistant and has long service life.

4. Low temperature butterfly valve packing box elevation design can withstand the expansion and contraction caused by low temperature medium to temperature change, to ensure that the sealing part will not leak.

5. drive mode is manual, worm drive, pneumatic, electric.
