Manual radiator valves

Manual radiator valves - a key element of efficient heating

Manual radiator valves are an indispensable element of every heating installation.   At Onninen, we understand their importance perfectly. Our many years of experience allow us to offer the highest quality products. Every day, we advise our customers on the selection of optimal solutions. These valves enable precise regulation of the flow of the heating medium. Thanks to them, the temperature can be adjusted in individual rooms. This translates into user comfort and energy savings.

Types of manual radiator valves in the Onninen offer

Our range includes a wide selection of manual radiator valves. We offer products from renowned brands such as Valvex, Ferro, Danfoss, Flamco Meibes and Imi Heimeier.   We especially recommend angle and straight radiator valves.   The former are suitable for installations with a side approach. Straight valves are dedicated to lower connections. We also offer double valves, combining supply and return functions. For the convenience of users, we offer return valves with the possibility of draining water. They facilitate maintenance and repairs of the installation.

Many customers ask us about complete solutions. That is why we have prepared radiator sets and shut-off units. They contain all the necessary elements to connect the radiator. In the case of modernization of the installation, we recommend Raditec radiator shut-off valves. They allow the replacement of the radiator without the need to drain the water from the entire system.

How to choose the right manual radiator valves?

Choosing the right manual radiator valve depends on many factors.   In our daily practice, we see how important an individual approach is. The type of heating system is crucial. Different valves are used in single-pipe systems, and different ones in two-pipe systems. The power of the radiator and the required flow of the heating medium are also important. The way the radiator is connected is also important - side or bottom. At Onninen, we always advise taking into account plans for the future. If later automation is planned, it is worth choosing valves adapted to thermostatic heads.

Our experience shows that the acoustic aspect is often overlooked. An incorrectly selected valve can generate annoying noise. That is why we recommend valves with pre-regulation. They allow for precise flow setting and noise elimination. In the case of buildings with high system pressure, we suggest using valves with a flow limitation function.

Practical applications of manual radiator valves

Recently, we were faced with a challenge when designing a large office complex. The client wanted to be able to individually control the temperature in each room.   We used manual radiator valves with thermostatic heads.   This allowed for precise temperature control and significant energy savings. In the case of office reorganization, we most often use valves with a shut-off function. They allow easy disconnection of the radiator without interfering with the entire installation.

In residential construction, we often encounter the problem of uneven heat distribution. The use of valves with pre-regulation allows for balancing the installation. Thanks to this, each radiator receives the right amount of heating medium. In older buildings, where there are large pressure fluctuations, valves with a flow limiter work well. They prevent overheating of rooms and noise in the installation.

Onninen also recommends solutions for public utility buildings. In schools and hospitals, we use tamper-proof valves. They provide stable temperatures and protect against unauthorized changes to settings. For hotels and guesthouses, we offer valves with remote control. They allow for central heating management and cost optimization.

Manual radiator valves are the foundation of efficient and comfortable heating.   At Onninen we offer comprehensive advice on their selection and installation. Our team of experts will help you choose the optimal solution for each project. We invite you to contact us and take advantage of our extensive experience in the field of heating technology.
