Please select either the desired flow rate of your valve or the size of your working connections: If you do not know exactly which size to take, you can determine the size of the connections using a simple rule:
The working connections of the valve are usually the same size as the connections of the application, for example the connections of the cylinder that is controlled with it!

In special cases, in the case of very intensive work cycles and high speeds that must be maintained, it is advisable to calculate the necessary flow for the valve or to contact our customer service, who will be happy to help you at any time.
