The ZVpP-100 vacuum valve with pneumatic actuator equipped with 100mm conditional passages is designed to overlap vacuum systems in the pressure range from 1x10-6 to 1,07x105 Pa (from 0,75x10-8 to 800 mm Hg). The ZVpP-100 vacuum pneumatic shutter is manufactured in the climatic version of the UHL placement category 4 (i.e. for moderate and cold climate) according to GOST standard 15150-69. The working environment is air and non–aggressive gases. The temperature of the working environment is from plus 1°C to plus 40°C. The vacuum valve with a pneumatic actuator is not intended for use in fire and explosive hazardous industries. The ZVpP-100 vacuum pneumatic shutter consists of a mechanism, a housing and a pneumatic actuator. The pneumatic actuator includes a pneumatic cylinder, on the piston of which a permanent magnet is installed to determine its position by means of magnetic position sensors "Closed" and "Open" fixed on the cylinder body and a distributor into which compressed air is supplied through a fitting. The speed of the pneumatic cylinder in particular and the operation of the shutter as a whole are regulated by rotating the pneumatic throttle head, if the pneumatic throttle heads are fully tightened, then the speed of opening and closing the shutter will be maximum. The solenoid, powered by a connector, serves as a distributor control device and is applicable in standard production conditions where the relative humidity of the air is not higher than 75%.
