FAQ (Frequently Asked Questions)
- What does “EEx ia” mean for this positioner?
It means “Intrinsically Safe.” The V18345-1017121001 can work in Zone 0, the most hazardous area where explosive gas is always present. Its electrical circuits cannot cause a spark. - How does “fail-freeze” work differently from “fail-safe”?
Fail-safe moves the valve to a pre-set safe position (open/closed) on failure. Fail-freeze holds the valve exactly where it was when the failure happened. This model can do both, chosen during setup. - Is the digital feedback kit included?
No. This specific model comes without pre-installed feedback modules. However, you can add a mechanical kit with proximity switches (SJ2-SN) for digital valve position signals if needed. - Can I use it with any single-acting actuator?
Yes, the single-acting pneumatic output is designed for spring-return actuators. Ensure your actuator’s air pressure range matches the positioner’s 1.4-6 bar supply. - Why is low air consumption important?
Low consumption (under 0.03 kg/h) reduces the load on your plant’s air compressor system. This saves significant energy costs over time, especially with many valves.
