Vacuum Flat-through gates with electric drive ZVPlE with nominal width 500, 630 and ZVPL with conditional passages 630, 900, 1200 are designed to cover the vacuum system in the pressure range from 1,33 10-3 10-5 to 1 Pa (1 10-5 to 760 mm Hg. cent.).
Operating environment - air and non-corrosive gases.
Electric power supply from the AC 220/380 V, frequency - 50 Hz.
The shutter in the closed position to withstand the pressure drop 1,07 10-5 Pa (800 mm Hg. Hg.) from either side of the valve.
The design allows for maintenance and repair without removing the valve. The shutter works in the installation position:
horizontal slide gate down;
horizontal slide gate up;
drive vertically upwards;
vertically down drive.
Opening and closing the shutter when supplying compressed air to pneumatic actuators. Management is carried out with the air control panel.
