Control valve selection and recommendation

In order to select the right product for your application it is recommended to have the following information available:

• Working conditions
• Maximum flow
• Minimum flow
• Continuous flow
• Maximum inlet pressure
• Minimum inlet pressure
• Wanted outlet pressure
• Pipe size

Strainers and Isolating Valves

To filter out impurities that could damage the control valve it is highly recommended to install a protection strainer on the inlet side. Additionally, isolating valves located either side of the control valve enable ease of commissioning and maintenance.

There is an extensive range of AVK gate valves available in a number of configurations. Isolating control valves - we recommend the standard AVK flanged gate valve, with short face-to-face length, or the variant prepared for an actuator.

For in-depth information about our gate valves go to the gate valve section and datasheets or alternatively by clicking on the products listed  below.

Air Valves

In many cases it is recommended to install an air valve at the inlet of the control valve in order to avoid trapped air pockets in the system. Air
pockets can sometimes cause increased energy consumption, operation costs, pressure loss and increase the risk of water hammer.

AVK have an extensive air valve range. For control valve installations, we recommend our combination air valves of reinforced polyamide or ductile iron. Information about AVK air valves is  on the datasheets found through our product finder or by clicking on the products listed below.
