Diaphragm check valves

Diaphragm check valves - the key to installation efficiency

Diaphragm check valves are an essential element of many hydraulic systems.   At Onninen, we understand their importance perfectly. Our experience shows that the right selection of these components is crucial. It affects the efficiency and reliability of the entire installation. That is why we offer a wide selection of diaphragm check valves.

We often come across questions about the differences between valve types. So let us explain that diaphragm check valves are distinguished by a flexible diaphragm. It acts as a closing element. This makes these valves great for many applications. This is especially true for systems with contaminated media.

Types of diaphragm check valves available from Onninen

Our range includes various types of these devices. We offer both threaded and flanged check valves. Each of them has its own unique features and applications.   Our experience shows that selecting the right type is crucial to the effectiveness of the system.

Among the available brands you will find products from renowned manufacturers. We especially recommend our own brands: Onnline and FXA. They are characterized by high quality of workmanship and competitive prices. They are an excellent choice for customers looking for reliable solutions.

• Threaded check valves - ideal for smaller installations
• Flanged check valves - suitable for large industrial systems

Criteria for selecting diaphragm check valves

When selecting the right diaphragm check valve, several key factors must be considered. The first is the type of medium flowing through the system. This has a huge impact on the durability and efficiency of the valve. Another important aspect is the system's operating parameters.

In our daily practice we see how important it is to match the working pressure and working temperature.   Incorrect selection can lead to failure or suboptimal operation of the installation. That is why we always advise our clients based on the specific requirements of their projects.

The material of manufacture is another key element. At Onninen, we offer valves made of various materials. These include stainless steel, brass and plastics. Each of them has its advantages and limitations. The selection depends on the specifics of the application.

Recently, we faced a challenge with a project for a large production plant. It was about selecting valves for a chemically aggressive medium. Thanks to our experience and wide range of products, we found the optimal solution. We used specialist valves with appropriately selected membrane material.

Practical applications of diaphragm check valves

Diaphragm check valves are widely used in various industries. In water supply systems, they prevent water from flowing back. In chemical installations, they protect against the mixing of substances. In the food industry, they ensure that the process is hygienic.

Our experience shows that they are particularly useful in systems with suspensions or high-viscosity liquids.   The flexible membrane effectively copes with such media. It ensures tight closure even with a small back pressure.

In the case of reorganization of production lines, we most often encounter the need to modernize existing installations. Here, diaphragm check valves often prove to be an ideal solution. They allow for the optimization of flows and increased process efficiency.

• Water treatment systems
• Industrial installations with aggressive media
• Production processes in the food industry
• Cooling systems in the energy sector

It is worth emphasizing that proper maintenance of diaphragm check valves is crucial for their durability. At Onninen, we offer not only the products themselves, but also professional advice on their operation. Our specialists are happy to share their knowledge on proper installation and periodic inspections.

In short, diaphragm check valves are extremely versatile and effective components of hydraulic systems. Their proper selection and application can significantly affect the efficiency and reliability of the entire system.
