This series of check valves adopts flow driven control, which can achieve high-speed isolation without additional sensors or driving subsystems, thereby reducing structural complexity and fault risk. Under a pressure difference of 1 bar, the response time from triggering the reflux pulse to complete isolation is less than 10 milliseconds, which is industry-leading among similar products.
As a safe isolation solution for vacuum systems, the GP-25.7 series avoids adding additional flow resistance to the system in its design, and its special flow optimization design achieves a perfect balance between high flow conductivity and fast isolation.
In gas flow processes containing by-products (such as front-end pipeline applications), conventional check valves are prone to reducing flow conductivity and affecting isolation capabilities due to the accumulation of pollutants. The GP-25.7 series effectively suppresses the deposition of most by-products through a special surface coating, and can be equipped with heating function to prevent process gases from condensing on the valve surface, thereby maintaining long-term stable operating performance.
