SIMPLIFIED ILLUSTRATION: FOOTVALVE INSTALLATION

A foot valve is a special type of check valve that has a built-in strainer. It is installed at the intake
side of a suction pipe and pump. Its purpose is to prevent the loss of prime when the liquid source
(wet well) is lower than the pump. Prime is defined as the charge of liquid required to begin
pumping action and priming is the process of filling the pump and suction pipe with liquid.

The check valve part of the foot valve opens when the pump starts to allow liquid to enter the
suction pipe and pump. When the pump stops, the check valve closes and prevents the liquid from
emptying. Thus the foot valve eliminates the need to prime the pump each time it is started. The
strainer component of the foot valve helps to remove unwanted debris from the liquid that may
cause damage to the pump.

In this type of installation, it is common to install a butterfly valve and a strainer on the suction side
of the pump. The butterfly valve is used to isolate the pump and the strainer provides additional
straining capacity.

Additional Design & Technical Notes:

• The FV 50-DI is designed to t Cast Iron ANSI

Class 125 and Ductile Iron ANSI Class 150
Flanges. The bolting pattern for Cast Iron
ANSI Class 125 and Ductile Iron ANSI Class
150 are identical.

• Ductile Iron body maintains the anti-
corrosive properties of Cast Iron while
achieving a yield strength comparable to
Carbon Steel. Ductile Iron also offers
higher pressure & temperature ratings
than Cast Iron.

• Screens are available in either basket
shaped or cone shaped. A wide variety
of perforations, meshes, and materials are
available for screens.

• Resilient seats (Buna-N) are available upon
request. Please contact factory.
