GDC-5型电磁高真空挡板阀是连接在真空管路上，用来接通或截止真空系统中的气流，或作充气阀用。当通电时将P、A端管路接通、断电时切断P、A端管路，保持P端真空系统的真空度。适用介质为纯净空气和非腐蚀性气体。

■ GDC-5 Electro High Vacuum Flapper Valve     ■ GDC-5 electro high vacuum flapper valve is mounted in vacuum pipeline to put through or cut off the airflow in vacuum system, or used as a charging vale. When power is connected, pipes at P and A will be put through, and when power is disconnected, pipes at P and A will be cut off, to keep the vacuum system at P vacuum. Applicable medium can be pure air and noncorrosive gases.
