Description
Ball
Valve
A ball valve is a structure that opens and closes a spherical ball
with a through-hole by rotating it 90 °. It is mainly used for
opening and closing. Normally, soft sheet is attached to both ends
of the ball to prevent leakage and to have high sealing force.
Compared to other types of valves, they are compact and lightweight
with very low pressure loss.
Ball valves using soft rubber sheets, such as general rubber, can
not be used at temperatures over 260 ° C, but ball valves for high
temperature at 600 ° C have also been commercialized as the metal
sheet structure has been developed. Manufacture of ball valves with
high reliability at high temperatures due to low adhesion to balls
and durability in high-temperature environment of metal sheet
requires high technical perfection. Metal sheet ball valve has
disadvantages that it is difficult to manufacture because it is
difficult to manufacture, but it has a wide use range (high
temperature, high pressure, slurry, powder, etc.)
