This article describes the development of 150 mm diameter all-metal ultra-high vacuum flapper valve and its application in large astronomical electronic camera. Described the device structure, performance and exhaust test results. The results of the joint venting test between the valve and the electronic camera tube indicate that the performance of the valve meets the gating requirements for the preparation and protection of photocathodes for large astronomical electronic cameras and general ultra-high vacuum exhaust systems.
