Air vent valve - ALFA, nickel-plated, automatic with shut-off valve 4700170

Air vent valve – reliable removal of air from the installation

This automatic air vent valve with an shut-off valve is a key element of every heating or water installation. Its task is to effectively remove accumulated air, which can cause disruptions in the proper functioning of the system – from reduced heating efficiency to noisy operation and corrosion. The ALFA model, made of nickel-plated brass, combines durability and functionality, ensuring long-lasting and trouble-free operation.

Construction and application

The ALFA air vent valve is designed to automatically remove air from the installation. The built-in shut-off valve allows easy isolation of sections of the installation for maintenance or repair without having to drain the entire system. Compact dimensions make it easy to install even in tight spaces. Nickel-plated finish provides corrosion resistance and aesthetic appearance.

The valve finds application in:

• Central heating installations (CH)
• Domestic hot water installations (DHW)
• Solar systems
• Industrial installations requiring venting
• Panel and ribbed radiators – especially where a traditional manual air vent is difficult to access.

Key features and benefits

• Automatic operation: Eliminates the need for manual venting of the installation, saving time and effort.
• Shut-off valve: Allows isolation of a fragment of the installation without having to drain it – facilitates service and repairs.
• Durability: Made of high-quality nickel-plated brass, resistant to corrosion and mechanical damage.
• Compact dimensions: Facilitate installation in tight spaces.
• Wide temperature range: Trouble-free operation up to 110°C (according to PN10 specification).
• Easy installation: Standard 1/2 inch thread ensures compatibility with most installations.
• High reliability: Ensures effective air removal, protecting the installation from failures and reduced efficiency.
• Pressure resistance: Designed to operate at a maximum pressure of PN10 – standard requirements for most domestic installations.

The valve body is made of CW617N nickel-plated brass, which ensures its durability and corrosion resistance. The inner diameter is 1/2 inch, and the maximum working pressure is PN10, while the maximum working temperature is 110°C. The valve has a GZ external thread for connection to the installation.

The ALFA valve is an investment in the trouble-free operation of your installation for years to come. Its automatic function and solid construction ensure comfort of use and minimize the risk of failure. This solution is appreciated by both professional installers and end-users who value reliability and convenience.
