Backwash Filter Pool Multiport Valve , Filter Multiport Valve ISO9001 Certificate

The magnet of the motor uses a custom rare earth permanent magnet, and the motor has a small positive and negative torque error. At the same time, precise transmission gears are used to ensure high adjustment accuracy.

This electric ball valve is stable for long periods of time under high flow conditions and is ideal for use in industrial refrigeration systems/equipment. Its easy-to-maintain features can also help improve the efficiency of industrial refrigeration system repair and maintenance, and bring more business opportunities to industrial refrigeration system manufacturers.

This valve is widely used in automatic backwash disc filtration system, driven by the pressure of pipelines and realize filter’s backwash automatically. It is simple-structured, practical, and can run for a long time without maintenance. The diaphragm can change the direction of stream quickly and stably. When backwash inlet is open, the water inlet is closed, or vice versa. It can avoid overflow of filter or mixing of clean water and waste water.

Filtration Model

The upper chamber decompresses by releasing the water or air source pressure. the fluid pressure inside the valve expands the diaphragm upword ,closing port A and allowing port B to flow out of port C.

Backwash Model

The upper chamber increasdes by adding source air or water pressure. The diaphragm will move down to close port B, and open port A. This will allow water to flow back through the valve from port C and exit through.
