Main Technical Performance.
1. Leakage rate: ≤ 1.3 × 10-9Pa.M3/S;Working Principe
The pneumatic high vacuum butterfly valve changes the direction of the air circuit through an electromagnetic directional valve, controls the actuator cylinder to drive the butterfly valve to open and close, achieving the purpose of connecting or cutting off the airflow in the vacuum pipeline. The applicable medium is pure air or non corrosive gas. Optional feedback signal device and electrical valve locator.
