FAQ

What is the significance of the "NG6" designation?

NG6 (from the German "Nenngroesse 6") refers to the nominal size 6mm port diameter. It corresponds to the CETOP 3 and NFPA D03 mounting interface standards, ensuring interchangeability between valves from different manufacturers that adhere to this standard.

No, this valve is specifically designed for a 230V AC power supply, as indicated by "EW230" in the type code. Using a 24V DC supply will not provide enough power to actuate the solenoid and may damage the power source or the coil.

The symbol shows a 4/2 directional valve, meaning it has four ports (P, T, A, B) and two switching positions. The diagram for spool type "D" indicates that in its spring-centered (de-energized) position, port P (pressure) is connected to T (tank), and ports A and B are blocked.
