Oiltech Controls Limited’s Insight
- Professional Review: The V18345-2010421001 is specifically prized for its Fail-Safe logic in double-acting configurations. Upon signal loss, it ensures the actuator reaches its safety limit by depressurizing output 1 while pressurizing output 2.
- Diagnostic Capability: The unit offers sophisticated internal diagnostics, including deviation monitoring and stroke counters, accessible via the local display or LKS adapter.
- Ideal Applications: Critical control loops in chemical processing, power plants, and large-scale rotary damper systems where precise valve positioning is non-negotiable.
- Application Tip: To ensure long-term stability of the I/P converter, maintain supply air quality according to ISO 8573-1 Class 2/3.

Technical Selection FAQ
- How does the “Fail-Safe” action operate on this specific model?
In a power failure, the V18345-2010421001 vents Output 1 and pressurizes Output 2 to move the valve to its designated safe state. - Is the analog position feedback module already installed?
Yes, the “1” suffix in the configuration confirms the 4-20mA plug-in module is included for position signaling. - What is the function of the LKS adapter port?
It allows for an easy connection to a PC for advanced configuration using FDT/DTM software without breaking the loop. - Can this unit be mounted on linear actuators?
Absolutely, the case is designed for universal mounting to DIN/IEC 534 (NAMUR) linear actuators and VDI/VDE 3845 rotary actuators. - Selection Guide: Why choose the NPT connection over the G thread?
The 1/2-14 NPT and 1/4-18 NPT connections are standard for North American projects, ensuring seamless compatibility with local conduit fittings.
