CCD Series
Electric Ultra-High-Vacuum Screw Gate Valve
CCD electric ultra-high-vacuum screw gate valve relies on the electric actuator to drive the stem to bring along the valve plate to make up-and-down movements so as to open or close the valve for the purpose of connecting or cutting off the airflow in the vacuum pipeline.The applicable media include clean air or non-corrosive gases.It is provides with a feedback signal device. |
