Regulating valves

Control valves - a key element of hydraulic systems

Control valves are   essential components in modern hydraulic and heating installations . Their role in controlling the flow and temperature of media cannot be overestimated. At Onninen, we understand the importance of these devices perfectly. Our wide range includes various types and models of control valves. We offer products from renowned brands such as Danfoss, Imi Ta, Afriso, Esbe and Taconova. Thanks to this rich offer, we are able to meet even the most demanding projects.

In everyday practice, we observe a growing interest in control valves. This is due to their key role in optimizing system operation.   Correctly selected valves allow for significant energy savings and improved comfort of use of the installation . Our customers often ask about the criteria for selecting the right valve. The answer depends on many factors. The most important are the installation parameters, the type of medium and the required precision of regulation.

Types of control valves available from Onninen

Our range includes a wide selection of control valves. We offer, among others:

• 3-Way Rotary Mixing Valves
• Control sets with mixing valves and electric actuators
• 3-way mixing valves DN 20-50
• Flanged mixing valves DN 40-80
• Thermostatic mixing valves
• Temperature valves

Each of these types has its unique uses and advantages.   Rotary 3-way mixing valves are perfect for central heating installations . They allow precise control of the heating water temperature. In turn, control sets with electric actuators allow for automation of the regulation process. This is an ideal solution for modern, intelligent buildings.

Flanged mixing valves DN 40-80 are used in larger industrial installations. Their solid construction guarantees reliability even in difficult working conditions. Thermostatic mixing valves are a simple and effective solution for regulating the temperature of utility water. They provide protection against scalding and a stable outlet temperature.

Criteria for selecting control valves - what to pay attention to?

Choosing the right control valve is a key decision for the efficiency of the entire system. At Onninen, we advise our clients, taking into account a number of important factors. First of all, the required flow and pressure drop must be determined. These parameters allow you to select a valve with the right characteristics. The type of medium and the operating temperature are equally important. Some valves are dedicated to specific applications.

Precision of regulation is another key aspect when choosing a valve . For systems requiring precise temperature control, we recommend valves with electric actuators. They allow smooth regulation over a wide range. For simpler applications, thermostatic valves will work well. They provide a stable temperature without the need for additional automation.

It is also worth paying attention to the material of the valve. In the case of drinking water, it is necessary to use valves made of corrosion-resistant materials. For chemically aggressive media, we recommend valves made of stainless steel or with appropriate protective coatings. Our offer includes products adapted to various working conditions.

Practical applications of control valves in modern installations

In our daily practice, we encounter various applications of control valves. We recently implemented a project for a large office complex. The key challenge was to ensure a comfortable temperature in individual zones of the building. We used a system based on mixing valves with electric actuators. This allowed for precise temperature control in each room.

Another interesting example is the modernization of the hot water system in a hotel. The problem was the fluctuation of the water temperature in the taps.   The use of thermostatic mixing valves has effectively eliminated these inconveniences . Hotel guests can now enjoy stable water temperatures without the risk of scalding.

In the case of industrial installations, we often encounter the need to regulate the flow of high-temperature media. This is where large-diameter flanged valves come in handy. Their solid construction guarantees reliability even in extreme conditions. We recently delivered such valves to a chemical production plant. The customer appreciated their precision of operation and resistance to aggressive media.

We are also increasingly seeing the use of control valves in underfloor heating systems. Here, precise control of the supply water temperature is key. 3-way rotary mixing valves are perfect for these applications. They allow for smooth temperature control, ensuring optimal thermal comfort.

Our experience shows that the right choice of control valves has a huge impact on the efficiency of the entire system . That is why we always carefully analyze the customer's needs before presenting a recommendation. At Onninen, we offer not only products, but above all professional advice. Our specialists will help you choose the optimal solution for each installation.
