Back Flushing Control Valves (Casting)

Backwash Control Valves are specialized hydraulic valves designed to provide highly efficient and reliable cleaning in filtration systems. These valves feature a 3-way control mechanism operated by line pressure or external pneumatic pressure and automatically manage filtration and backwash (backwash) modes in filtration systems. Thanks to the integrated diaphragm assembly, the valve provides control in both directions, directing water flow to the correct mode.

In filtration mode, the valve performs the cleaning function by forcing water through the filter elements. During the transition to backwash mode, the diaphragm assembly reverses direction, opening the discharge path and allowing water flow through the back of the filter.

This mechanism prevents mixing of clean and dirty water and ensures maximum efficiency of the filter elements. This reduces the risk of filter clogging, extends maintenance intervals, and ensures continuous efficient system operation.

Backwash Control Valves are preferred in a wide range of applications, including industrial
filtration systems, drinking water facilities, agricultural irrigation, and wastewater treatment systems. Thanks to their durable construction and precise diaphragm control, the valve provides long-lasting, pulse-free, and reliable performance. It provides high filtration efficiency with minimum intervention to system operators.
