The 2ZVE-250R vacuum shutter with electromechanical drive equipped with 250mm 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-250R shutter is pendulum-type. The 23VE-250R shutter is manufactured in the climatic version 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 and explosive hazardous industries. The 23VE-250R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, the gate belongs to Class I electrical equipment according to GOST 12.2.007.0-75.

Vacuum resistance furnaces are necessary for heating products before pressure treatment, for sintering, degassing, quenching, annealing, soldering and chemical-technological processes. Such furnaces among all the variety of thermal equipment are considered the most environmentally friendly – heat treatment is carried out at t up to +2500 ° C in a purified vacuum. Under certain conditions, vacuum furnaces are used to work with neutral gases. The outer part of the furnace is made of stainless steel and is cooled by liquid. The inner part of the working chamber, where the heat treatment of materials is carried out, is made of an alloy of molybdenum and tungsten. The components are characterized by a low inertia force, reduced gas separation. The settings are available on the control panel, where the instruments, automatic and manual control switches are located. At every enterprise of the electronic industry, nuclear power, an explosion-proof vacuum resistance furnace is needed. The same applies to areas where various products undergo heat treatment at the stage of production and preparation for use.
