The electric brake valve is applied to various lines of DN50 to DN600, PN10 to PN160, for truncating or switching media in the line. Different materials, the national standard gate valves of Xwo Technology can be applied to water, steam, oil, nitric acid, acetic acid, oxidative medium, urea, etc. The driving method of the national standard gate valve is manual, gear drive, pneumatic or electric. The Z41H national latter gate is generally used with flanges, or the weld is also used.

The national standard electric shutoff valve is suitable for various lines of DN15 to DN200, PN16 to PN160, for truncating or turning on the medium in the line. Different materials, the national standard cutoff valve of Xwo Technology can be applied to water, steam, oil, nitric acid, acetic acid, oxidative medium, urea and other media. The driving method of the national standard intermittent valve is manual, gear drive, pneumatic or electric. The national standard shutoff valve is generally used with flanges, or the welding connection can also be used.

The national standard gate valve is suitable for various pipelines of DN50～DN600, PN10～PN160, used to cut off or connect the medium in the pipeline. Choose different materials, the national standard gate valve of Xianwo Technology can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and so on. The driving mode of the national standard gate valve is manual, gear transmission, pneumatic or electric. Z41H national standard gate valve generally adopts flange connection, but also can adopt butt welding connection.

The opening and closing parts of the globe valve are plug-shaped flaps, the sealing surface is flat or tapered, and the flaps move linearly along the center line of the fluid. The movement form of the valve stem includes the lifting rod type (the valve rod is raised and lowered, the hand wheel is not raised and lowered), and the lifting rotary rod type (the hand wheel and the valve rod rotate and lift together, the nut is provided on the valve body). The shut-off valve is only suitable for fully open and fully closed, and it is not allowed to adjust and throttle.

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 and so on. Cast steel swing check valves are generally flanged or butt welded.
