Penglai Huande Steel Valve CO., LTD.

Internal And External Threaded Ball Valve

Welcome to Penglai Huande steel valve Co., Ltd. And we are a professor of floating ball valve production. This is an internal and external ball valve.

It has been known that an internal thread ball valve can also be made into internal and external thread ball valve. Q11F internal ball valve, also called double-head inner ball valve, is mainly threaded. This valve is made of forged steel, so it can withstand high temperature and high pressure, and its diameter is generally less than DN25. The material has 304, 316, which is widely used in petrochemical engineering, chemical industry engineering, electromechanical engineering equipment, electric control electromechanical engineering equipment pipeline.



We can design any kind of internal and external floating ball valve within our de-wax craftwork. And we warmly welcome you to ask for any information of our company and products.

The butt-weld, on the other hand, is more complex because there is no socket alignment, and the ends of both the pipe and the valve must have matching bevels as well as be in perfect alignment during the welding process. The initial welding pass in butt-weld joints is called the root pass. It requires skill and practice to perform correctly. The root pass is followed by subsequent passes until the weld is completed.

We export both sockets welded ball valves and butt welded ball valves according to the requirements of our customers and we also take charge of any quality problems.
Since welding will always have a place in valve manufacturing because of the impracticality of casting or forging some alloys or material combinations. We are continuing to improve our production technology and help our clients to open global valve market.
