Describe
The body of the j41y/j40h large-diameter American standard stop valve adopts a spherical structure and is beautiful in appearance. The valve seat disc has a conical sealing structure and the seal is reliable. American standard flange stop valve is applicable to various lines of Class150~2500, working temperature 29~425°C (American standard cast steel stop valve) or -196~600°C (stainless steel American standard cut-off valve) for cutting or picking The medium in the pipeline. It is used to cut off or turn on the medium in the pipeline. It can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium and urea.
 
J41y/j40h large diameter American standard globe valve features
1. The shape of the valve body is spherical or streamlined and beautiful. The flow shape is straight-through and the fluid resistance is small.
2. The valve disc and seat sealing pair adopt cone surface seal, the seal is reliable, the debris is not easy to fall on the sealing surface, the closing force is small, the erosion resistance and the sealing are reliable.
3. The valve seat can be a replacement valve seat, which can be combined with the closing sealing material to meet the requirements of working conditions and prolong the service life.
4, large-diameter, high-pressure shut-off valve according to the need of the closing force of the valve stem transmission mode using a lifting rod, and equipped with a rolling bearing type of bevel gear to reduce the closing force.
5. The material of the valve body, valve disc, valve stem, packing and fastener can be reasonably matched according to the actual working conditions, so as to be suitable for a variety of different working conditions.
