GP-14.0 - High vacuum gate valve
The GP-14.0 high vacuum gate valve is designed specifically for reliable isolation in standard high cycle vacuum processes, meeting high standards of durability, modularity, and maintainability, with a particular emphasis on long-term stable operation and low purchase costs.
This series adopts GPTECH patented locking sealing technology, which provides reliable sealing while avoiding friction during the valve plate sealing process. The mechanical locking function of the closed end position effectively prevents valve malfunctions during operation, thereby maintaining stable performance under various application conditions.
Product Introduction
Product Parameters
This series adopts GPTECH patented locking sealing technology, which provides reliable sealing while avoiding friction during the valve plate sealing process. The mechanical locking function of the closed end position effectively prevents valve malfunctions during operation, thereby maintaining stable performance under various application conditions.
The GP-14.0 series has been put into use in thousands of high demand process environments, fully demonstrating its excellent reliability and becoming the industry standard for high vacuum isolation in the DN 63-400 mm (2.5 "-16") size range.
Its sturdy and lubricant free design meets all the performance requirements of reliable high vacuum gate valves, especially suitable for high-frequency process cycle operation, setting a benchmark in the field of high vacuum gate valves.
This series offers multiple drive modes and flange connection options, making it easy to integrate into various vacuum systems. At the same time, multiple specialized configurations can also be selected, such as roughing, exhaust or metering ports, and alternative sealing materials, to ensure the best match for different application needs.
