FAQ

What is the significance of the ‘NG10’ size designation?

NG10 (also known as CETOP 5) refers to the standardized mounting interface of the valve according to ISO 4401. This ensures that the valve is interchangeable with other NG10 valves from different manufacturers, regarding port locations and mounting bolt patterns.

Can this 205V DC valve be operated with a different voltage?

No. The solenoid coil is specifically designed for 205V DC. Applying a different voltage, especially a much lower or higher one, can lead to malfunction, overheating, or permanent damage to the coil. Always use the specified voltage.

How do I use the concealed manual override (N9 feature)?

The concealed manual override (N9) is a safety and maintenance feature. It is typically a push-pin located under a protective cap. It allows you to shift the valve spool manually without electrical power, which is useful for system setup, testing, or emergency operation.
