Plate check valves

Disc check valves - the key to efficient hydraulic installations

Disc check valves are an indispensable element of modern hydraulic systems.   At Onninen, we understand their importance for the reliability of the installation. Our experts advise on the selection of optimal solutions every day. We make sure that the products offered meet the highest standards of quality and efficiency.

Plate check valves play a key role in preventing the reverse flow of liquid or gas. Their design is based on a movable plate that opens under the influence of the medium pressure. When the flow stops, the plate closes, blocking the movement in the opposite direction. It is a simple, yet extremely effective solution.

Types of plate check valves available from Onninen

Our range includes various types of plate check valves. We offer models adapted to various media and operating conditions. Among them, we distinguish:

• Plate check valves for water and neutral liquids

• Plate check valves for gas installations

We pay special attention to the quality and reliability of our products.   That is why our offer includes renowned brands, including our own brands: Onnline and Fxa. They guarantee an optimal combination of functionality, durability and attractive price.

Selection criteria for plate check valves

The right choice of a plate check valve is crucial to the efficiency of the installation. Several important factors should be considered in the selection process:

• Type of working medium
• Working pressure and working temperature
• Required tightness
• Material of manufacture
• Installation method

Our experienced consultants will assist you in selecting the optimal solution.   We analyze the specifics of a given installation and propose the best options. Thanks to this, customers can be sure that the selected valves will meet their expectations.

In everyday practice, we often come across questions about the differences between plate check valves and other types. It is worth emphasizing that plate valves are characterized by low flow resistance. They are used in installations where minimizing pressure losses is important.

Practical applications of plate check valves

Disc check valves are widely used in various branches of industry and infrastructure. Recently, in a project for a large chemical plant, we delivered specialist valves for aggressive media. Their proper selection ensured safety and efficiency of production.

In water supply systems, disc check valves play a key role in protecting the network.   They prevent water from flowing back, protecting sources from contamination. In fire protection systems, they ensure that water is available at critical moments.

We often encounter challenges related to the modernization of older installations. In such cases, plate check valves are an excellent solution. Their compact design makes them easy to install in limited space. At the same time, they provide high operational efficiency.

In refrigeration and air conditioning systems, plate check valves protect compressors. They prevent refrigerant from flowing back, which could lead to serious damage. They increase the service life and reliability of the entire installation.

Disc check valves play an important role in pumping installations.   They protect pumps against water hammer and prevent emptying of the pressure pipelines. As a result, the period of failure-free operation of the system is significantly extended.

At Onninen we also offer specialist plate check valves for aggressive media. They are used in the chemical and petrochemical industries. Their proper selection guarantees the safety and reliability of production processes.

Many customers ask us about the possibility of using plate check valves in gas installations. We offer models specially adapted to work with technical and flammable gases. They provide high tightness and safety of use.

Our experience has shown that proper valve installation is crucial.   That is why, in addition to the products themselves, we also offer expert technical advice. Our specialists are available to help with proper installation and operation.

In everyday practice, we observe a growing interest in non-return plate valves in RES systems. They are used in solar and geothermal installations. They secure the circulation of the working medium, increasing the efficiency of the entire system.

Onninen recommends the use of plate check valves in industrial installations. Their reliability and durability translate into reduced production downtime. As a result, they contribute to increased efficiency and reduced operating costs.

Disc check valves are an indispensable element of modern, efficient installations.   Their correct selection and application translates into the reliability and safety of the entire system. At Onninen we provide comprehensive support - from selecting the right product to expert technical advice.

We invite you to familiarize yourself with our wide range of plate check valves. Our experts will be happy to help you choose the optimal solution for a specific application. Thanks to many years of experience and a wide range of products, we are able to meet even the most demanding projects.
