Tecnidro - Model 3V Series -Backwash Hydraulic Controls Valves

The backwash valve 3V Series ensures:

• ease of installation
• significant reduction of maintenance operations
• long service life in the open field
• excellent quality / price ratio

The backwash valves are automatic hydraulic valves because:

• the opening and the closing are operated by the water pressure in the same pipeline (not require external auxiliary energy sources to perform the maneuvers);
• they automatically convert from the opening position (filtration line of the filter) to the closed (flush outside of impurities) and vice versa, thanks to an hydraulic control circuit.

The design of the diaphragm and the excellent hydrodynamic profile of the metal body gives the product a water flow rate greater than other types of valve, thus resulting in a minimal head loss.

The right valve position (open, closed or moving) is continuously indicated by the operating shaft, made of stainless steel, which comes out from the cover.
