Select the right control valve

The following conditions should be taken into consideration in order to select the right solution for your application:

• Working conditions

• Maximum flow

• Minimum flow

• Continuous flow

• Maximum inlet pressure

• Minimum inlet pressure

• Wanted outlet pressure

• Pipe size

Our online sizing tool provides guidelines for the selection.

Strainers and isolating valves

It is highly recommended to install a protection strainer on the inlet side to filter out impurities that could damage the control valve. Isolating valves on each side of the control valve facilitate commissioning and maintenance.

AVK gate valves are available in a vast number of configurations. For isolating control valves, we recommend our standard flanged gate valve with short face-to-face length or the variant prepared for actuator. Find in-depth information about our gate valves at the gate valve section.

Air valves

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

AVK air valves are available in many variants. For control valve installations, we recommend our combination air valves of ductile iron or reinforced polyamide.
