11. API 602 forged steel globe valve: This kind of globe valve is designed according to the American Petroleum Institute standard API 602, the valve body and bonnet are forged of carbon steel or stainless steel.
9. Upper thread stem globe valve: The stem of this type of globe valve is not in direct contact with the working medium. According to the shell material, sealing pair material, packing material, valve stem material, suitable for different working conditions.
7. Globe valve for oxygen pipeline: The valve is designed in strict accordance with the requirements of oxygen pipeline. The stuffing box part is strictly sealed, and external dirt must not enter the stuffing box.
5. High temperature and high pressure power station globe valve: the structural feature of the valve body and the valve cover is that the connection between the valve body and the valve cover adopts pressure self-tightening sealing type or clamping type, the connection form between the valve body and the pipeline is butt welding connection, the valve body material is mostly made of chromium-molybdenum steel or chromium-molybdenum vanadium steel, and the sealing surface is mostly overcast cemented carbide.
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.
