3. Angle globe valve: The biggest advantage of the angle globe valve is that the valve can be installed at the corner of the pipeline system, which saves 90O elbow and is easy to operate. Therefore, these valves are most suitable for use in synthetic ammonia production systems and refrigeration systems in fertilizer plants.
4. Steel ball or porcelain ball sealing globe valve: the structural feature of the valve is that the valve body is divided into conjoined type and split type, and the valve disc is STL cemented carbide steel ball or porcelain ball made of amorphous material by powder forming, high temperature sintering and fine research. The lower end of the stem rolls the envelope ball in the stem ball hole, and the ball can produce countless sealing lines when it rotates in three dimensions in the ball hole of the valve stem, which greatly increases the service life of the sealing surface and ensures reliable sealing. Due to the limitation of ball sealing, this valve is generally used for smaller nominal sizes, about DN6 ~ DN25. The valve is suitable for high temperature and high pressure steam pipelines in nuclear power plants and thermal power plants, instrument pipelines of sampling and sewage systems, and temperature, pressure, wear and corrosion resistance pipelines in petrochemical and chemical systems.
