The China Backwashing Valve is activated by pipeline pressure or an external pressure source, and programmable control can be realized by adding a solenoid valve, and the sewage can be flushed regularly. The China Backwashing Valve can automatically switch between two working modes according to the working conditions of the filtration system and system settings. One is a filtration mode that allows impurity-laden water to flow directly through the water outlet to the filter. The other is the mode in which the China Backwashing Valve disconnects the passage between the water ports, opens the sewage outlet, and then flushes the filter to remove impurities.

The high reliability of the China Backwashing Valve ensures long-term stable operation without maintenance. Its diaphragm-driven structure requires only a short stroke to smoothly change the direction of water flow, closing the water inlet when the backwash port is open and vice versa. The China Backwashing Valve prevents filter overflow or mixing of clean water with waste water.
The Backwashing Valve has a simple structure, is easy to install and saves investment, and has super hydraulic performance. The moving parts of the China Backwashing Valve run smoothly, are positioned accurately and are chemically resistant materials. The China Backwashing Valve is suitable for a variety of medium water flow to turn quickly, with high flushing efficiency and high reliability.
