Middle or low pressure valve normal adopt taper disc sealing structure, but the large diameter and high pressure valve adopt sideway disc sealing structure, the medium flow from high to low position, it use medium self pressure seal, so the sealing is very reliable and the operated torque is more light. According to condition, the valve can be apply more kinds of material and connection type between bonnet and body and can be reach to more requirements of user.
