⌈ MAIN CHARACTERISTICS ⌋

•Glofa fully welded ball valve are in integral full welded full sealing structure by forging and fabricated process, there is not any bolt connection throughout the body. Absolutely no leakage at the middle and bonnet joints position. Comparing to other types of valves, the full welded ball valve have unique advantage of no defects that generated in the castings, no need to disassembling the valve components frequently on the pipeline, resulting in extending the valve service life greatly and saving the spare parts like flanges, bolts, gaskets. The series ball valve seat are made of PTFE with *5% carbon fiber and spring loaded, high adaptation to the weather changes. When the pipeline pressure get higher or less, the loaded spring could force the ball and seat surface keep in touch tightly and achieve zero-leakage all the way.

⌈ DESIGN ADVANTAGES ⌋

•The fully welded ball valve could be buried underground and just require building one small well station on the ground. The stem could be extended or shortened according to pipelines condition demands. The valve body materials could be same as the connected pipelines, thus avoid occuring stress uneven and got good welding property. Glofa fully welded ball valve is bi-directonal sealing which allow the flow pressure from both ends, the valves is with ability of pressure self-relief. Comparing to gate valves or butterlfy valves, the fully welded ball valve would not make the medium loss during the flow, the series valves are the optimum selection for thermal power and natural gas services.
