Vacuum Valves With An Electromechanical Drive 2ZVE
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.
