Purpose:
Urban gas: gas output pipelines, main and branch supply pipelines, etc. 
Central heating: large heating equipment output pipelines, main lines, and branch lines. 
Heat exchanger: opening and closing of pipelines and various circuits. 
Steel plant: various fluid pipelines, exhaust gas discharge pipelines, gas and heat supply pipelines, fuel supply pipelines. 
Various industrial equipment: various heat treatment pipelines, various industrial gas and heat pipelines. 

characteristic:
One piece welded ball valve, without external leakage or other phenomena Due to the carbon fiber reinforced PTFE seal and butterfly spring of the valve seat, it has strong adaptability to changes in pressure and temperature, and any leakage may occur within the marked pressure and temperature range. The processing of the sphere is tracked and detected by advanced computer detectors, so the precision of sphere processing is high.
Due to the fact that the valve body material is the same as the pipeline material, there will be no uneven stress, and there will be no deformation due to earthquakes or vehicles passing through the ground. The pipeline is resistant to aging. The sealing ring body is made of RPTFE material with a carbon content of 20%, ensuring complete zero leakage (0%).
Directly buried welded ball valves can be directly buried underground without the need to build large valve wells. Only small shallow wells need to be set up on the ground, greatly saving construction costs and project time. The length of the valve body and the height of the valve stem can be adjusted according to construction and design requirements. The processing accuracy of the sphere is very precise, the operation is easy, and there is no adverse interference.
