DHW safety valves

DHW safety valves - a key element of the water installation

DHW safety valves are essential components of every domestic hot water installation.   Their role is crucial for the safety and proper functioning of heating systems. At Onninen we offer a wide selection of these devices. Our range includes products from renowned brands such as Syr, Afriso and Flamco Meibes.

DHW safety valves protect the installation from excessive pressure increase. They operate on the principle of automatic water release. Thanks to this, they prevent damage to other system elements. In our daily practice, we see how important it is to select these devices correctly.

Types of DHW safety valves available at Onninen

Our offer includes various types of DHW safety valves. These include:

• Brass safety valves
• Valves with different connections
• Valves with different opening pressure values
• Valves in different pressure classes

Each of these types has its specific uses and characteristics.   Selecting the right valve depends on many factors. These include installation parameters, type of water heater and legal requirements.

How to choose the right DHW safety valve?

Choosing the right DHW safety valve is crucial for the safety of the installation. The main selection criteria are:

• Maximum operating pressure of the installation
• Thermal power of the water heater
• Connection diameter
• Required valve capacity

In our experience, a common mistake is to underestimate the required bandwidth.   This may lead to insufficient protection of the installation in emergency situations.   That's why we always recommend consulting our specialists before making your choice.

Recently, in a project for a large housing estate, we advised on the selection of DHW safety valves. The client initially considered a cheaper solution. After analyzing the installation parameters, we proposed valves with a higher capacity. This decision turned out to be crucial for the safety of the entire system.

Many customers ask us about the differences between diaphragm and spring valves. Diaphragm valves are more sensitive to pressure changes. They work better in installations with variable loads. Spring valves, on the other hand, are more resistant to difficult operating conditions.
