FAQ

What is the significance of the 'N9K4' designation in the model number?

The 'N9K4' code specifies that the valve is equipped with a concealed manual override, allowing for manual actuation without electrical power, and it uses an electrical connector according to the DIN EN 175301-803 standard.

Yes. The '/V' at the end of the type code indicates that the valve is fitted with FKM (Viton) seals, which are compatible with a wider range of fluids, including phosphate esters and certain synthetic fluids, compared to standard NBR seals. Always verify fluid compatibility with the manufacturer's datasheet.

The '6' in the model name corresponds to a nominal size of 6 (NG6), which adheres to the CETOP 3 mounting standard. This ensures interchangeability with other valves that follow the same standard.
