Globe Valve

Widely used in fields such as petroleum, chemical engineering, metallurgy, construction engineering, water supply, etc

American standard globe valves mainly have APIASME standards and ASTM material standards, not the standards of the valve itself; Globe valves designed, manufactured, produced, and tested according to American standards are called American standard globe valves.

American standard globe valves mainly have APIASME standards and ASTM material standards, not the standards of the valve itself;
Globe valves designed, manufactured, produced, and tested according to American standards are called American standard globe valves.

Productadvantages

1. The fluid resistance is small, and its resistance coefficient is equal to that of pipe sections of the same length.
2. Simple structure, small size, and light weight,
3. Tight and reliable, currently plastic is widely used as the sealing surface material between gates, with good sealing performance. It has also been widely used in vacuum systems.
4. Easy to operate, quick to open and close, with a 90 degree rotation from full open to full close for remote control.
5. Convenient maintenance and simple structure. The sealing ring is generally movable, making disassembly and replacement more convenient.
6. When fully open or fully closed, the sealing surfaces of the valve body and valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the sealing surface of the intermediate door.
7. Wide application range, with diameters ranging from a few millimeters to several meters, from high vacuum to high pressure. When the ball rotates 90 degrees,
The outlet should be completely spherical in order to cut off the flow.
