Se estrikti a nan ranfòse a te adopte, epi li se desen an Streamline nan plak la valv reyalize, epi li se bon jan kalite a Distribisyon nan sifas la plak valv amelyore, epi li se rezistans a koule redwi. Bag nan asye pur monte sou kò a, kòm estrikti a kòn, fezab nan sikilasyon likid, men tou, amelyore bon jan kalite a Distribisyon nan kavite anndan an nan kò a valv, diminye rezistans a koule.

The structure of the truss is adopted, and the streamline design of the valve plate is realized, and the casting quality of the valve plate surface is improved, and the flow resistance is reduced. The stainless steel ring mounted on the body, as the cone structure, conducive to fluid circulation, but also improve the casting quality of the inner cavity of the valve body, reduce the flow resistance.
