2-way control and shut-off valves

2-Way Control and Shut-Off Valves - The Key to Effective Flow Control

2-way control and shut-off valves are the basis of modern hydraulic systems.   At Onninen we offer a wide range of these key components. Our products guarantee precise control of the flow of liquids and gases. They are used in many industrial and construction sectors.

The range includes various types of valves. These include ball valves, zone valves and two-way control valves. Each of them has a specific function in the system. Ball valves provide quick flow cut-off. Zone valves allow for control in separate areas. Control valves, on the other hand, allow for precise control of the flow rate.

Wide range of 2-way valves for various applications

In our catalog you will find products of renowned brands. We offer valves from Danfoss, Imi Ta, Naval, Taconova and Vexve. Each of these brands is famous for its reliability and innovation.   Thanks to this diversity, we can tailor the solution to each project.

Our offer also includes additional accessories. These include disinfection modules, thermometers and drive adapters. They allow for comprehensive equipment of the installation. They ensure its proper functioning and easy maintenance.

Selection criteria for 2-way control and shut-off valves

Choosing the right valve requires taking into account many factors. The technical parameters of the installation are key. The operating pressure and temperature of the medium must be taken into account. The required capacity and regulation accuracy are also important.

• Type of medium (water, gas, oil)
• Nominal diameter of connections
• Material of the body and seals
• Control type (manual, electric, pneumatic)

In our daily practice we encounter a variety of design challenges.   We recently helped select valves for a large office complex. The client needed precise temperature control in individual zones. We used Danfoss zone valves in combination with room thermostats. The result was a significant improvement in work comfort and energy savings.

Another example is the modernization of a production line in a food plant. Ensuring the hygiene of the installation was key. We used Naval ball valves with a certificate for contact with food. Additionally, we installed disinfection modules to increase safety.

Practical applications of 2-way valves in various industries

2-way control and shut-off valves are widely used. They are used in heating and cooling systems of buildings. They are essential in industrial and process installations. They are an important element of fire protection systems.

When reorganizing offices, we most often use zone valves.   They allow for individual temperature control in each room. This translates into employee comfort and effective energy management. Imi Ta brand products are great for this purpose.

In industrial plants, we often use two-way control valves. They enable precise control of the flow of process media. This is crucial for maintaining production parameters. In such applications, we recommend reliable Vexve valves.

Domestic hot water systems are another area of application. This is where Taconova's thermostatic domestic hot water valves come into their own. They guarantee that the water temperature remains constant. They prevent scalding and ensure comfort of use.

In our daily practice, we see a growing interest in automation. Customers increasingly ask about valves with electric drives. They enable remote control and integration with BMS systems. For such applications, we recommend Danfoss valves with dedicated adapters for drives.

• Heating and air conditioning systems
• Industrial and process installations
• Water and sewage networks
• Fire protection systems
• Gas installations

Our experience shows that the correct selection of valves is crucial for the efficiency of the entire system.   We often encounter situations where an incorrectly selected valve causes problems. This may be insufficient temperature control or flow instability. That is why professional advice at the design stage is so important.

At Onninen, we offer not only products, but also technical support. Our specialists will help you choose the best solutions. They will advise you on assembly and operation. Thanks to this, customers can be sure that their installations will function reliably.

It is worth paying attention to the maintenance of valves. Regular inspections and cleaning extend their service life. In the case of control valves, periodic calibration is important. It ensures that the regulation accuracy is maintained. For these purposes, we offer specialist tools and accessories.

2-way control and shut-off valves are a fundamental element of every hydraulic installation.   Their correct selection and operation are crucial. They affect the efficiency, safety and economy of the entire system. At Onninen, we understand these relationships. That is why we offer comprehensive solutions tailored to the needs of our customers.

We invite you to contact our technical advisors. They will help you select the optimal valves for your projects. Together we will find a solution that meets all technical and economic requirements.
