Hansen logo Choosing the correct foot valve

Hansen foot valve Use the following flow chart and technical specifications to determine the correct Foot Valve for your requirements
Foot Valve selection instructions

Step 1: Measure or calculate the capacity of your pump installation.

Step 2: Look at the chart for the valve(s) that cover the flow rate.

Step 3: For dirty water applications choose the largest valve that will be operating in the area shown               by the thicker line.

Example: If your pumping capacity is 400 l/min use a FV32 Foot Valve
