The quality Backwashing Valve products is a special hydraulic control valve that is driven by the pressure of the pipeline system. The Backwashing Valve is like a multi-way connecting pipe in appearance, which can automatically switch between the two-position and three-way, so as to realize the automatic backwashing of the filter.

The most common application area for the quality Backwashing Valve products is in various types of filtration systems. The Backwashing Valve is used in automatic backwash filter systems with at least two parallel filter units. That is, in the process of backwashing of the quality Backwashing Valve products, the clean water filtered by one filter unit is used as the wash water of another filter unit.
