Vacuum closures with electromechanical actuator 2ZVE with orifices 100, 160, 250 and 400 mm, are designed to overlap the vacuum systems at pressures of from 1 10-6 to 1,07 105 Pa (0,75 10-8 to 800 mm Hg. cent.) on the pipelines for air and non-corrosive gas operating temperature up to 40 0C. Ambient 1 400C.
The gates are not designed for use on fire - explosive productions.
The gate opens at a differential pressure across the valve is not more than 1,3 103 Pa (10 mm Hg. Cent.) At a higher pressure on the throttle and not more than 1,07 105 Pa (760 mm Hg. Cent.) - at a higher pressure under the flap.
