Serving high-end applications with ball valves for high temperatures and abrasive mediums is within our unique expertise developed over decades. Meticulously engineered, constructed and tested with careful metallurgical selection of all valve parts, using special surface finishing and treatments, hard coatings, and thorough analyses of mechanical strength and thermal expansion, ensure that our High Temperature (metal seated) valves are a proven choice for the industries toughest and most demanding applications.
1. Advanced seats: Seats designed based on years of experience in ball valve manufacturing to ensure valve sealing, low friction coefficient, small operating torque, a variety of seat materials, a wide range of applications.
2. Switch without error handle: use flat head stem, the connection with the handle will not be misplaced, so as to ensure that the switch state indicated by the handle and the valve are consistent.
3. Locking device: In order to prevent valve switch from misoperation, there are locking holes in the fully open and fully closed position of the valve to ensure that the valve is in the correct position.
4. Stem anti-flying structure: the stem is downloaded to prevent pressure flying out, and can form metal contact with the valve body after fire to ensure stem sealing.
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.
