The national standard cut-off valve is suitable for various pipelines from DN15 to DN200 and PN16 to PN160, used to cut off or connect the medium in the pipeline. With different materials selected, Xianwo Technology's national standard globe valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc. The drive method of the national standard globe valve is manual, gear transmission, pneumatic or electric. The national standard globe valve is generally flanged or butt welded.

The cast steel swing check valve is suitable for various pipelines of Class150 ～ Class2500 and PN20 ～ PN420 to prevent backflow of the medium in the pipeline. Choose different materials, Xianwo Technology's cast steel swing check valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc. Cast steel swing check valves are generally flanged or butt welded.

In the American standard gate valve, there are single gate, double gate and elastic gate. The single gate wedge gate valve is simple in structure and reliable in use, but it requires high precision for the angle of the sealing surface, and is difficult to process and maintain. The possibility of wedging when the temperature changes is very high. Double gate wedge gate valves are used more frequently in water and steam medium pipelines. For applications where the temperature exceeds 260 ° C, Xianwo Technology recommends the use of flexible or split wedge gates as internal gate valves to prevent the wedge gates from being stuck due to thermal expansion. When used in high-speed fluid (turbulent flow) or thermal cycle applications, to avoid loosening, the threaded seat ring should be welded to the valve body.

Stainless steel forged gate valve is applicable to various pipelines of Class150 ～ Class1500 and PN16 ～ PN100, used to cut off or connect the medium in the pipeline. Different materials are used. The stainless steel forged gate valve of Xianwo valve is suitable for various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and so on. The drive mode of stainless steel forged gate valve is manual, gear transmission, pneumatic or electric. Stainless steel forged gate valves generally use flange connection, but can also use butt welding connection.
