Modernized version of the usual window pane can be called a ventilation air inlet valve. A well-designed valve design regulates the constant circulation of fresh air. A simple, quiet design of the valve fits neatly into any interior. Everything would be great! Yes, only the incredible price of a modest valve inhibits the acquisition. And what if ... Of course, try it!

About the benefits of the air intake valve
It is known that the guarantee of excellent health is the life-giving air in the apartment. If you are sure that opening windows and ventilation pans for airing will improve the air exchange in the house or apartment, then this is self-deception.
Normalize the quality air exchange in the apartment in full capacity is only a ventilation system. The ventilation system consists of exhaust and supply ventilation, the main purpose of which is the removal of harmful gas-air formations and emissions from the dwelling.
There are the following ventilation systems for private houses and apartments:
- general-purpose intake and exhaust devices and heat recovery
- ducted inlet and exhaust devices
- window inlet valves
- wall and built-in wall valves supply.
The supply air is designed to supply a certain volume of air mixture. For a complete circulation cycle of air exchange, special devices and devices are used - supply valves. The supply valve can be installed on windows and built into walls.
The installation of the supply valve is recommended to be performed in accordance with the regulations in force: SNiP 41-01-2003 "Heating, ventilation and air conditioning" and 6.8 TR ABOK-4-2004 "Technical recommendations for air exchange in apartments of a multi-storey residential building". Particularly popular is the air infiltration valve - supply valve kiv.
The technology of installing a ventilation wall inlet valve
The supply valve is a simple design that can be installed manually. The installation technique will be to create a passageway in the wall and directly install the valve. In the place recommended by the rules and regulations (above the heating battery), a mounting channel with a diameter slightly larger than the valve pipe is drilled.
The flow of air passing through the installed plastic pipe will flow into the installed noise absorber. Due to the labyrinth form of the sound absorber, it cuts out street noise and reduces the air flow rate. Then, through the adjustable damper of the valve, the air flow enters the radiator in the longitudinal direction.
The proximity of the radiator allows the air temperature to reach room temperature. Therefore, the inflow of air is evenly distributed into the room.
The design of the ventilation ventilation valve
The inlet wall valve consists of the following elements:
- channel (pipes) made of plastic with a diameter of 133 mm
- inner head with flap
- outer head with lid
- outer mesh grating
- heat and noise insulation
- o-ring
- air filter
- control knobs.
All valve elements are supplied by the manufacturer in a general kit.
How to install the supply valve with your own hands
factory valve installation
The valve is installed in the following sequence:
In the indicated place of the wall above the heating radiator, drill a hole 68 mm in diameter to a depth of 100 mm for the pipe channel.
In the resulting hole, install the pipe of the channel. Outside the edge of the pipe should be at the level of the street wall.
The outer part of the pipe is closed with a screen grid. The inner part of the pipe should protrude by 6 mm. Excess will need to be cut off.
On the inner part of the pipe we put on the pipe insulation. Then we make a marking for the installation of the soundproof enclosure. The pipe should be placed in the middle of the mounting holes. Drill holes for fastening.
We mount the valve body against the wall with self-tapping screws. The body must press the heater.
In the plastic housing we install a noise absorber and an adjusting damper. Close the case with a plastic cover.
The process of installing the valve with your own hand is shown in this video.
Naturally, it is not difficult to produce such a factory-manufactured supply valve from prefabricated elements. But the nice home masters are used to doing everything with their own hands. Therefore, it is time to make a valve from improvised materials. For example, ventilation grilles of household "VENTS", plastic pipe and foam rubber.
homemade supply valve
The household ventilation grille "Vents" is a good set for creating a supply air valve. Functions of the channel will be ensured safely by the plastic pipe. Complexity will consist in creating a noise isolation labyrinth filter.
Recall that the filter class EU3, used in the original design of the valve, is made of a porous synthetic material. The main function of the filter is to clean the incoming air from the dust.
Original filter element and noise insulation, for example air supply valve Domvent, consists of five layers of foam rubber welded together by hot air.
The plastic case with a set of foam plates has an elongated rectangular shape. At the bottom, the structure is divided by a jumper into two compartments. In each compartment there is a separate foam pad. The compartments have separate external exits in the form of narrow apertures. The flow of air from the street enters the common hole, from where it is distributed along the compartments.
The design is simple, so it is possible to make a soundproof labyrinth with your own hands. More detailed information on the design of the noise-proof design of the supply valve is presented in this video.
After the manufacture of the soundproof structure and the filter, the valve is set up in a manner similar to the instruction for the factory production valve.
