Plate / flap check valves

Plate/flap check valves - an essential element of hydraulic installations

Plate/flap check valves are key components in hydraulic systems . They prevent the backflow of liquid or gas in the system. In our daily practice, we see how important a role they play in ensuring the correct flow of media.

We offer a wide selection of check valves from renowned manufacturers. In our assortment you will find products of the Ferro, Valvex and Socla brands. Each of them guarantees the highest quality and reliability.

Types of wafer/flap check valves available at Onninen

We offer a variety of check valve types. Models are available in diameters from 1/2 to 3 inches. We are often asked about the differences between them. Here are the main types:

• Flap check valves 1/2-3 inches
• TIGER PLUS 1/2-2 inch metal stem check valves
• TIGER spring check valves brass 1/2-2 inches
• Wafer check valves type 802 and 895

Each type of valve has its own unique properties and applications . Selecting the right model depends on the specifics of the installation and the requirements of the project.

Selection criteria for plate/flap check valves

When selecting a check valve, there are several key factors to consider. The first is the diameter of the pipeline. It must correspond to the size of the valve. The next is the type of medium flowing through the system.

The operating temperature of the system is also important. It influences the selection of the valve material. The operating pressure is another important parameter. It determines the valve's resistance to loads.

Our experience shows that it is also crucial to consider the flow direction . It affects the orientation of the valve installation in the system. Recently, in a project for a large industrial plant, this aspect turned out to be critical.

For systems with frequent pressure changes, we recommend valves with a metal stem. They provide better operating stability. For installations with aggressive media, we recommend models made of special alloys.

Practical applications of plate/flap check valves

Plate/flap check valves are widely used in various industries. In water supply systems, they prevent water from flowing back. In heating systems, they maintain proper circulation of the medium.

In the chemical industry, they protect against the mixing of substances. In air conditioning systems, they regulate the flow of the refrigerant.   Our experience shows that they are essential in every professional plumbing installation .

We often come across questions about specific projects. In one of our recent projects for a production plant, we used TIGER PLUS valves. They ensured stable operation of the machine cooling system.

In the case of the modernization of the city's water supply network, we used type 895 inter-flange valves. Their durability and reliability have proven themselves in difficult working conditions.

For customers in the food industry, we recommend stainless steel valves. They meet strict hygiene standards. In a recent project for a dairy, this solution proved to be ideal.

Many customers ask us about energy-saving solutions . In this context, it is worth mentioning spring valves. They minimize pressure losses in the installation. This translates into lower operating costs.

In fire protection systems, we use quick-response valves. They guarantee immediate shut-off of the flow in an emergency. This is crucial for the safety of buildings and their users.

For installations with frequent changes in flow direction, we recommend swing valves. Their design allows for operation in both directions. This solution works well in complex hydraulic systems.

At Onninen we offer comprehensive support in selecting valves. Our specialists will help you choose the optimal solution. We will take into account the specifics of your installation and design requirements.

Our experience shows that an individual approach is key . Each project has its unique requirements. That is why we analyze the client's needs and select the right products.
