Central heating safety valves - a key element of heating installations

Central heating safety valves are essential components of every central heating installation.   Their main task is to protect the system from excessive pressure increase. In our daily practice, we see how important a role these inconspicuous devices play. They ensure safety and long-term operation of the entire heating system.

Our wholesale offer includes a wide selection of CO safety valves. Models with different parameters and purposes are available. We offer valves with connections from 1/2 inch to 2 inches. Working pressures range from 1.5 bar to 8 bar. Valve power ranges from 50kW to 900kW.

Types of CO safety valves and their applications

Our range includes several main types of safety valves:

  • Diaphragm valves - the most popular in home central heating installations
  • Spring valves - used in larger facilities
  • Full-Lift Valves - for Industrial Installations
  • Proportional valves - providing smooth regulation

Selecting the appropriate central heating safety valve is crucial for the proper operation of the system.   We often come across the question of selection criteria. The most important parameters are the opening pressure and valve capacity. They must be adapted to the boiler power and installation capacity.

Recently, in a project for a large housing estate, we used 350kW safety valves. They provided optimal protection for the extensive central heating installation. In the case of smaller single-family houses, valves with a capacity of 50-100kW work well.

Leading manufacturers of CO safety valves in the Onninen offer

In our wholesale, we focus on proven brands. We offer products from renowned manufacturers such as Syr, Afriso, Caleffi and Flamco Meibes.   Each of these manufacturers is renowned for the high quality and reliability of their CO safety valves.

Our experience shows that Syr valves are great for home installations. For larger facilities, we recommend Caleffi products. Afriso valves are valued for their precision. Flamco Meibes is a good choice for industrial installations.

When upgrading older heating systems, we often recommend replacing safety valves. New models offer better protection and are more reliable. Many customers ask us about the possibility of self-installation. We always recommend using the services of a qualified installer.

Practical aspects of using CO safety valves

Correct selection and installation of the central heating safety valve is the basis for safe operation of the heating system.   In our daily practice, we see how important this issue is. An incorrectly selected valve can lead to serious failures.

We often come across a situation where a customer wants to save money on a safety valve. This is the wrong approach. It is better to invest in a high-quality product. It will provide long-term and failure-free operation. In the long run, it simply pays off.

Onninen recommends regular inspections of the central heating safety valves. It is best to carry them out once a year, before the heating season. This allows you to detect any faults and prevent more serious failures. The inspection checks the valve for tightness and correct operation.

In the case of reorganization of the central heating system, it is most often necessary to replace the safety valve. The new system may have different operating parameters. This requires adjustment of the safety devices. Our specialists will be happy to advise on the selection of the appropriate valve for the modified system.

Many customers ask us about the possibility of using CO safety valves in other installations. We usually advise against such solutions. Each type of installation has its own specific requirements. It is better to use valves dedicated to a given system.

Central heating safety valves not only protect the installation, but also provide peace of mind to users.   Knowing that your system is well-secured allows you to enjoy thermal comfort without worries. At Onninen, we make every effort to deliver the highest quality products.

We invite you to familiarize yourself with our full offer of CO safety valves. Our technical advisors will be happy to help you choose the optimal solution. We guarantee professional support at every stage of project implementation.
