V18345-1010421001
ABB
The ABB V18345-1010421001 is an ATEX-certified intelligent electro-pneumatic valve positioner from the TZIDC series, configured for double-acting actuators with fail-safe function and 4–20mA analog position feedback. The ATEX Ex ib IIC T6 certification makes it suitable for use in potentially explosive atmospheres (Zone 1/2). With auto-calibration, sub-0.5% accuracy, and IP65 aluminum housing, it is widely deployed in oil and gas processing, chemical plants, refineries, and pharmaceutical manufacturing where both precision control and explosion protection are required.

Q: What is the ABB V18345-1010421001?
A: The V18345-1010421001 is an ATEX-certified TZIDC intelligent electro-pneumatic valve positioner configured for double-acting actuators with fail-safe function and analog position feedback.
Q: What ATEX certification does this model have?
A: It is certified ATEX Ex ib IIC T6, suitable for installation in Zone 1 and Zone 2 hazardous areas where explosive gas atmospheres may be present.
Q: What does "double-acting, fail-safe" mean?
A: Double-acting means it controls both sides of a piston actuator. Fail-safe means that on loss of electrical power or signal, the positioner drives the valve to a predetermined safe position (fully closed or fully open), critical for safety shutdown applications.
Q: How does this differ from the V18345-1010521001?
A: The key difference is position 4 (explosion protection) and position 5 (output/safe position). The 1010421001 has ATEX certification and fail-safe operation; the 1010521001 has no explosion protection and fail-freeze operation.
