Safety valves and valve pipes are crucial components in all pressurized HVAC systems, such as heating systems, boiler systems and tap water systems. The main function of a safety valve is to automatically protect the system against harmful overpressure by releasing water or steam when the pressure exceeds the set limit value. Valve pipes, in turn, direct the liquid further in a controlled and safe manner.
With us you will find a carefully selected range of high-quality safety valves, valve pipes and associated fittings from well-known manufacturers. The products are made of robust materials such as brass and are designed for long-term and reliable operation. Regardless of whether you are performing a new installation or maintaining an existing heating system, the correct valve and pipe routing ensures a safe and approved installation.

Buying guide for safety valves and valve pipes
Choosing the right pressure safety for your heating system or water installation is an important part of well-functioning property protection. Safety valves open automatically at a predetermined opening pressure to prevent pipes, water heaters or boilers from being damaged by excessive pressure levels.
Important features and areas of use
Each installation places specific demands on the specifications and dimensions of the valves. When planning your purchase, you should take the following factors into account:
- Opening pressure (Bar/MPa): Safety valves are available with different pressure settings, such as 1.5 bar, 2.5 bar, 6 bar or 9 bar. It is very important to choose a valve with an opening pressure that matches the maximum permissible working pressure of the installation.
- Connection dimensions: Check that the threads and connections (e.g. R15, G20 or compression fittings) fit your existing pipes.
- Material selection: Valves made of dezincification-resistant brass provide strong corrosion protection and a long service life in demanding environments.
- System type: Check whether the valve is intended for closed heating systems, tap water or specific boiler installations.
Things to consider before installation
Installation of safety valves and valve pipes should always be carried out in accordance with applicable industry regulations for Safe Water Installation. Always position the valve so that the overflow pipe or valve pipe can lead away waste water to a visible drain without risk of personal injury or water damage. Regular inspection and exercise of the safety valve is recommended to ensure that the mechanism functions flawlessly over time.
