Structural Features:
The stainless steel globe valve is a type of globe valve that requires high-quality body materials—commonly 301, 304, or 316—and is widely used in industries such as chemicals, shipbuilding, pharmaceuticals, and food machinery. These valves are available in manual, pneumatic, and electric versions.
a. The structure is simpler than that of a gate valve, making manufacturing and maintenance more convenient.
b. The sealing surfaces are resistant to wear and scuffing; the valve offers excellent sealing performance because there is no relative sliding between the disc and the body's sealing surface during opening and closing, resulting in minimal wear and a long service life.
c. The disc travel is short during operation, resulting in a lower overall height compared to gate valves, although the face-to-face length is greater.
d. Fluid resistance is high; the flow path within the valve body is relatively tortuous, leading to significant fluid resistance and higher energy consumption.
