Ball valves

Ball valves - essential elements of hydraulic installations

Ball valves are   key components in hydraulic and industrial systems . They are used to control the flow of liquids and gases in pipelines. Their simple, yet effective design ensures reliability. At Onninen we offer a wide selection of top quality ball valves. Our range includes products from renowned brands as well as our own brands.

Ball valves consist of a body and a rotating ball with a hole. By turning the ball 90 degrees, the flow can be completely opened or closed. This simple operating principle translates into high reliability. Ball valves also feature minimal pressure drop when fully open. This makes them suitable for many applications.

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

The selection of the appropriate ball valve depends on many factors. Key parameters include diameter, type of connection and material of manufacture. Maximum operating pressure and temperature are also important. At Onninen, we advise on the selection of optimal solutions. We analyze the specifics of a given installation and the customer's needs.

When choosing a ball valve, the type of medium should be taken into account . Different models are used for water, and others for gas or aggressive substances. The frequency of use of the valve is also important. In the case of infrequent opening/closing, it is worth considering models with PTFE sealing. They prevent the ball from seizing in one position.

In our daily practice, we often come across questions about valve selection. Recently, we advised on valves for a large industrial plant project. The client needed a solution for an installation with an aggressive medium. We proposed acid-resistant steel valves with PTFE seals. They proved to be excellent in these difficult conditions.
