Air Vents & Vacuum Valves

Plumbing Valves Air Vents & Vacuum Valves

Welcome to our category for air vents and vacuum valves, where we collect reliable components to optimize the function of your heating and cooling systems and sewage installations. Air in closed systems can lead to reduced efficiency, annoying noise and, in the worst case, rust damage to sensitive pipe parts. With the right equipment, you ensure that the system works flawlessly and that the flow remains stable over time.

Here you will find a carefully selected range of automatic air vents, vacuum valves, drain valves and practical air wrenches. Regardless of whether you need to supplement an existing heating system or install new components in a sewage system, we offer products from well-known manufacturers such as Durgo, Flamco and Altech. Our products are designed to meet high demands for operational reliability and long service life in both private homes and commercial properties.

Find the right air vents and vacuum valves for your systems

Maintaining the right pressure and keeping systems free of unwanted air is crucial for all types of HVAC installations. Air bubbles that collect in radiators or underfloor heating systems significantly impair heat transfer, leading to higher energy consumption. By installing efficient components, you protect the property's infrastructure and ensure a smooth and quiet flow.

Different product types and their unique benefits

Within this category, there are several specialized products that solve specific tasks in your pipe systems:

  • Automatic air vents: These valves continuously and automatically release accumulated air from heating and cooling systems without releasing any water, reducing the need for manual maintenance.
  • Vacuum valves: Mainly used in sewage systems to prevent negative pressure. They allow air into the system when flushing, which stops the water trap from emptying and prevents bad odors. The Durgo brand is particularly known for its high-quality designs in this area.
  • Magnetite filters and degassers: Advanced components from, for example, Flamco and Bosch that actively clean the system from both microbubbles and harmful magnetite particles, which extends the life of circulation pumps and heat exchangers.
  • Air bleeders and manual valves: Indispensable tools for traditional, manual air bleeding of individual elements and radiators.

Important things to consider before purchasing

In order for your installation to be completely correct and function optimally, there are some technical parameters that you should check carefully before finalizing your order.

First of all, the connection dimension is crucial. Check whether your system requires a threaded connection (internal or external thread, for example G15 or G20) or whether it is intended for press fittings and smooth pipe ends. It is also important to choose the right material and finish, such as robust brass or chrome-plated finishes, based on where the component will be placed and how visible the installation is.

Also consider the placement in the system. An air vent is most useful at the highest points of the system where air naturally collects, while a vacuum valve for drains must be mounted at the correct height and position to safely take in air in the event of negative pressure.
