The comfort of living and the European style of life dictate their own rules and requirements. Buy plastic windows can be both elite and economy class. To life was comfortable and in joy, it is necessary that all was well, even a brand new PVC window, which was installed with his own hands. It remains to install the supply valve on the window, so that the ventilation process is constant, even in the closed-leaf mode.

Supply valve for plastic windows
The existing problem of air exchange in our living quarters is relevant for virtually all PVC window owners. The multi-circuit sealing of plastic windows completely reduces the flow of fresh air from the outside with the door closed.
Therefore, condensation forms on the surface of the insulating glass unit. For the organization of air exchange in accordance with the "Recommendations on the organization of air exchange in apartments of multi-storey apartment houses" use a supply valve to the window.
What is a supply air vent
The ventilation supply air valve is a device that allows you to supply the required amount of air inside the room where the window is located.
Recall that, according to the regulatory requirements of SanPIN and regulatory documents for the microclimate of residential premises ISO and ASHRAE, for one person this rate is 30 cubic meters. air per hour.
The operating principle of the supply valve for PVC windows is based on creating and changing the flow section, which depends on the humidity characteristics of the air.
The design of the air supply valve
Structurally, the supply valve consists of the following elements:
• Enclosures with mounting strip
• Adjustment mechanism with lid
• springs and flaps
• the sensor drive.
The working channel of the airflow intake is a through slot. The valve regulating air intake has two states: open and closed.
The valve profile has a flat rectangular shape with three landing strips with holes for self-tapping screws and fixing dowels.
After replacing the fragments of standard seals and installing the valve, air enters the formed channel at the place of replacement, and then, passing through the valve, rushes into the room.
The functions of the mounting plate, which is mounted on the inside of the window in the upper part, allow to regulate the direction of air flow during ventilation of the PVC windows. These are the modes of "automatic ventilation" and the "micro ventilation" mode.
The external visor is equipped with an airflow limiter.
The air flow is monitored by means of a knob travel adjuster that drives the inner flap.
The installation of the supply valve is carried out in two ways:
• without milling the profile
• with milling.
Before buying a new device "for the home, for the family" we always sneakly read reviews, in each of which there is some truth.
The usefulness of the inlet valve to the window
Here is one of the responses: "My husband and I spent two hours reviewing this figovin on a photo of one of the online stores. To be frank, we did not receive much inspiration from this invention. Indeed, if the window of your apartment gets fogged up, then to install the valve makes sense.
But if the PVC window does not have a problem, then it is not entirely advisable to install a valve that provides airflow from the street with the door closed. This function can be safely ensured with the use of a micro-ventilation mode. "
And here is another review: "The supply valve, installed recently with his hands on the window, exceeded our expectations. The trinket at first glance turned out to be a convenient device capable of providing constant ventilation without opening the windows. "
To ensure the usefulness of the device, you just need to install the supply valve on the window and feel the intent of the manufacturers.
We install the supply valve on the plastic window
installation option without milling profile
Determine the location of the future valve on the opening window leaf. We cut out the regular sealant along the length of the valve (350 mm). In the places of the future fastening of screws we install two dowels. Remove the protective film from the valve seal.
We mount and fix the valve on the leaf using self-tapping screws. We install two seals of 160 mm length from the delivery set to the place of the standard seal. We replace the fragments of the regular sealant. We perform adjustment and monitoring of the operation of the installed valve.
version of the valve with profile milling
In some cases, there is a need for a valve with increased air permeability. The installation process does not differ from the installation of the valve without milling.
The only difference is the milling of the leaf to a depth of up to 15 mm, providing the necessary increased air flow of the open valve.
In the same way remove the standard seal, install the valve bar and fix it with screws. In addition, we additionally make the installation of the protective cap on the mounting insert from the kit and fix it with screws.
