Backwash control valves are 3-way control valves that operate with line pressure or external pneumatic pressure in filtration systems. The valve operates in filtration and reverse washing mode in coordination with the filter elements in the system. The diaphragm plug Assembly of the valve works 2-way. In the valve filtration mode, when switching to reverse wash mode, the valve opens the drain path by changing the direction of the plug. Thus, clean water in the system and dirty water mixture prevents the filter elements in the best way to clean.
