1.Without any friction between disc and sealing surface when opening or closing,
2.Can be installed in any position；
3.Zero leakage design;
4.Soft seat or metal seat is available as per customer request;
5.Unidirectional seal or Bidirectional seal is available as per customer request;
6.Spring loaded packing can be chosen;
7.Low emission packing can be chosen according to ISO 15848 requirement;
8.Stem extended design can be chosen;
9.Cryogenic temperature or ultra low temperature butterfly valve can be chosen as per customer request.
