Frontier manual and 2-way or 3-way pneumatic vacuum ball valves are used in vacuum systems with a range of 1 x 10-6 Pa to 1.2 x 10(5) Pa to start or cut off fluid flow. They can be used in various gas and liquid pipeline systems under both positive and negative pressure. The valve shaft rotates the valve ball 90 degrees to open or close the valve. The valve sealing seat scrapes off particle attachments on the ball surface during rotation. A sealing ring is embedded in the valve sealing seat, significantly enhancing the vacuum sealing performance. The pneumatic ball valve is offered in a 2-way or 3-way valve and can withstand positive pressure to meet the requirements for ultra-high vacuum systems. These are also suitable for accelerator vacuum systems. Manual and pneumatic ball valves are offered with DN16, DN25, DN40, DN50, DN63, DN80, DN100, DN160 and DN200 flange sizes.
