Abstract

There is provided a filter for a diaphragm valve. The filter attaches to a diaphragm of the valve and filters fluid entering a control chamber in the valve. The filter includes internal structure that increases the path from where fluid enters the filter through a mesh of holes to a single exit flow path leading to the control chamber. This increased path reduces the potential for debris in the flow to clog the exit flow path from the filter.
