When fluid is required in the direction of flow, the diaphragm opens allowing full flow. As the flow through the valve stops, the diaphragm closes preventing any return flow. The greater the back or head pressure, the better the diaphragm seals against the valve seat.
PREVENT PUMP DAMAGE WITH A
FOOT VALVE SOCK

This accessory for the Hansen Foot Valve is a Filter Sock designed to help filter and stop particles entering the Valve.

In addition to it's filtering properties, it has also proven successful in international applications by helping prevent the build up of troublesome marine life around the valve such as Zebra Mussels that can cause systems to block, resulting in pump damage.
