Globe valve is a valve whose opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. They can be tightly closed with only a 90 degree rotation and a small rotational torque. Ball valves are most suitable for use as switches and shut-off valves.
• The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment of the same length
• Simple structure, small size, and light weight.
• Tight and reliable, and the sealing surface material of the ball valve is widely used in plastic with good sealing performance, which has also been widely used in vacuum systems.
• Convenient to operate, quick to open and close, with only 90 ° rotation from full open to full close, facilitating remote control.
• Convenient maintenance, simple ball valve structure, and generally movable sealing rings make disassembly and replacement more convenient.
• Widely applicable, with diameters ranging from a few millimeters to several meters.
