API carbon steel steel stainless steel globe valve

API carbon steel steel stainless steel globe valve

What are the advantages of J541H globe valve?

1. American standard globe valve has simple structure, small size and light weight.
2. The valve is easy to operate, and the American standard globe valve opens and closes quickly, which is convenient for remote control.
3. Easy maintenance, simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
4. When fully open or fully closed, the sealing surface of the valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
5. The American standard globe valve has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum pressure.

5. The inverted seal is made of threaded connection sealing seat or body surfacing welding austenitic stainless steel, the inverted seal is reliable, the packing replacement and maintenance can be carried out without stopping the machine, which is convenient and quick without affecting the system operation.

Advantages of Welded Globe Valve

1. Leave a position for the valve handle to rotate.
2. Cannot be used as throttling.

        3 Ball valves with transmission mechanisms should be installed upright.

The working principle of carbon steel globe valve, American standard globe valve and American standard gate valve is to make the valve unblocked or blocked by rotating the valve. The gate valve is easy to switch, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easy to be eroded by the medium, and has been widely used in various industries.

Carbon steel globe valves are mainly used in pipelines to cut off, distribute and change the flow direction of media. Gate valve is a new type of valve that has been widely used in recent years.
