District heating、Cooling、Gas use directly buried all welded ball valve, there won't be the phenomenon such as external leakage. Because the seat is made of carbide, fluorine, sealing ring and cafe spring, so the ability to adapt to the change of pressure and temperature, the annotation of pressure and temperature range will not produce any drainage and smooth. Sphere with advanced computer processing detector tracking detection, so the sphere of high machining accuracy. Because the body material as pipe material, won't appear uneven stress, also won't because of the earthquake and the vehicle through the ground deformation, occurs when pipeline resistance to the old. Sealing ring ontology using 20% C (carbon) content of PTFE material, guarantee completely without leakage (0%). All welded directly buried type gas ball valve can be directly buried underground, need not build high large valve well, only need to set up small shallow Wells on the ground, greatly reduce the construction cost and project time.
Application
District heating,cooling and heating suppey systems.
The Use of medium
Water,air,oil and other fluids,which are not decomposing carbon steel.
