The body of the 50M URS valve is of welded construction and consists of a shell, a seat, side and lower nozzles. The lower branch pipe of the 50M URS valve is connected to the vacuum system using welding. The smooth part of the stem serves as a visual indicator of the "open" or “closed” valve positions. The casing is designed to protect the valve from accidental openings, and also serves as additional protection against precipitation, sand, dust entering the inner cavity of the valve. The valve opens when the flywheel rotates counterclockwise. The valve closes when the flywheel rotates clockwise.

The 2ZVE-400R vacuum shutter with electromechanical drive equipped with 400mm conditional passages is designed to overlap vacuum systems in the range of operating pressures from 1x10-6 to 1.07x105 Pa (0.75x10–8 to 800 mm Hg). The 2ZVE-400R shutter is pendulum-type. The 23VE-400R shutter is manufactured in climatic versions UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69. The working environment is air and non–aggressive gases. It is not intended for use in fire hazardous and explosive industries. The 23VE-400R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, it belongs to Class I electrical equipment according to GOST 12.2.007.0-75.

It is designed to prevent the flask from surfacing when it is thermostated in a laboratory bath or liquid thermostat.

The main advantage of the PRIZ prefix is the possibility of obtaining well–defined spectra of micro-objects after giving them the shape of a thin layer on mirror-polished metal plates (in the mode of the so-called double passage, when radiation twice penetrates through the layer of matter, reflecting from the mirror-substrate). The presence of a visual control system with a built-in video camera significantly increases the information content when setting up and the reliability of the results obtained. With the help of the prefix, it is also possible to register the reflection spectra of bulk samples and solid objects of arbitrary geometry in native form, including pharmaceuticals in the form of tablets, powders and granules, polymer fragments, LCP, films deposited on the surface. Technical specifications Transmission in the operating range of the spectrum, % of the input signal at least 40 The recommended number of scans when registering spectra is 25 Spectrum registration time at 25 scans (resolution 4 cm-1), sec 30 Minimum initial dimensions of a solid sample, mm 0.2 × 0.2 The maximum area of the solid sample, mm 20X20X10 Variable focus range, mm 10 The diameter of the focus spot, mm 3 The angle of incidence of radiation (central beam) on the sample in the ZDO 45o mode Micro lens magnification / total magnification of the 4X visual channel Field of view of the optical system, mm 2 X 2.5 The resolution of the digital video camera is 640x480 Overall dimensions, mm 140×105×160 Weight, kg 1.16

The ZVPlE-630 shutter consists of a housing with connecting flanges, a shutter mechanism, a lip seal to ensure the tightness of the drive element, cover, and electric drive. The shutter mechanism consists of a carriage, an upper and lower flap, which are pulled together by springs and balls. The carriage moves along the housing guides on bearings. The ZVPlE-630 shutter is opened and closed both by electric drive and manually using a flywheel. To switch to manual control mode, there is a switching device on the electric drive. The manual drive is used to adjust and adjust the shutter. ZVPlE-630 valves are manufactured in climatic versions UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69.
