It is small in size, light in weight, easy to transport, install, maintain and repair, and reliable in operation. The rotary ball valve includes a fully welded hard-sealed rotary ball valve made of forged steel. The valve body of the forged steel fully welded hard-sealed rotary ball valve is integrally forged and is not restricted by casting conditions. It is particularly suitable for the installation and use requirements of large-diameter hard-sealed valves in heating projects. It can be directly welded to the pipeline and has the general advantages of fully welded ball valves and hard-sealed rotary ball valves. Valve manufacturers do not need to invest a lot of mold costs and can adjust the valve body structure length and connection method according to order requirements. The forged steel hard-sealed rotary ball valve with a fully welded structure has a small overall size, which saves manpower and material resources for valve manufacturers, shortens the production cycle, and can effectively improve economic benefits. The forged steel hard-sealed rotary ball valve with a fully welded structure provides a better technical choice for heating pipelines where large-diameter valves need to be welded and the on-site installation size is limited.
