The 3KN-2,5 intake valve includes a nut, the filter is installed in the housing between the two rings. The opening of the inlet valve 3KN-2,5 is carried out when the electromagnet coil is de-energized and the armature returns to its original position under the mechanical pressure of the spring. The closure of the 3KN-2,5 intake valve occurs when an electric voltage of a certain power is applied to the terminals of the coil. The anchor is involved in the shoe, ensuring the closure of the ductal canal.

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%.

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 working condition of the ND-1000 diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. The working fluid is "VACMA OIL 500" vacuum oil (under technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-1000 diffusion pump is a maximum of 23 liters, a minimum of 16 liters. The viewing window for visual inspection of the working fluid has marks of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid practically does not change. The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of heaters in the ND-1000 diffusion pump using two temperature sensors. The temperature sensor must be installed in a special radiator socket above the heater. In the event that there is a loss of working fluid and an increase in the temperature of the radiators to 360 0C for the ND-1000 diffusion pump, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4°C to plus 25°C. The recommended cooling water consumption for the housing is 1500 l/h, for the oil reflector 150 l / h and is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break).
