The valve plate of the high-temperature sanitary ball valve and the sealing surface of the valve seat are oblique conical structures with temperature and corrosion-resistance alloy material welded on the inclined cone surface of the valve plate. These specialized alloys allow the valve plate and seat to withstand routine wear and tear caused by corrosive chemicals and abrasive mediums.

The spring fixed between regulating ring pressure plates is assembled together with the regulating bolt on the pressure plate. This structure effectively compensates for the tolerance zone between the sleeve and the valve body as well as the valve stem's elastic deformation from the system's high pressure. These components solve the valve's sealing problem in the process of two-way interchangeable medium transportation.

The differences of soft and hard sealing

The ball valve seat serves for sealing the fluid inside and uniformly distributing the seating stress. In soft seat ball valve designs, either the elastomer or polymer can be used as the seal. And due to different classification standards, thcharacteristics, performance and applicable working condition can also be different.
