Automatic hygroscopic air vent valve for radiators. 1/2 inch GZ male thread with PTFE seal. 508041

Automatic air vent – effective removal of air from the heating system

This automatic hygroscopic air vent is a reliable solution for removing air from radiators, ensuring quiet and efficient operation of the heating system. Equipped with a 1/2 inch GZ male thread with PTFE seal, this valve is easy to install and provides a tight connection. Its chrome finish gives it an aesthetic look, and the white acetyl resin knob makes it easy to operate.

Design and materials

The valve is made of high-quality brass (EN 12164 CW614N), which guarantees its durability and corrosion resistance. The PTFE seal ensures a tight connection, eliminating the risk of leaks. The mechanism of action is based on the principle of hygroscopy – a cellulose insert reacts to moisture, automatically opening and closing the valve depending on the presence of air in the system. This means that the venting process takes place automatically, without manual intervention.

Functionality and application

This valve works perfectly in both new and modernized heating installations. Its versatility allows it to be mounted in various types of radiators, and the ability to work in any position makes installation easy even in hard-to-reach places. The maximum working pressure is 10 bar, and the maximum working temperature is 100°C, which ensures safe and reliable operation under standard operating conditions. Additionally, the knob allows for manual control of the venting process – it can be set to three positions: automatic operation, valve open or completely closed. This gives the user full control over the system.

• Automatic operation: Eliminates the need for manual radiator venting, saving time and effort.
• High-quality materials: Brass body and PTFE seal ensure durability and corrosion resistance.
• Versatility: Can be mounted in various types of radiators and in any position.
• Simple operation: White acetyl resin knob makes adjustment and control of the venting process easy.
• Safety: Maximum working pressure of 10 bar and temperature of 100°C guarantee safe operation.
