Oiltech Controls Limited’s Insight
Our engineering team highlights the V18345-2010420001 for its superior double-acting fail-safe logic. Unlike standard single-acting units, this specific V18345-2010420001 configuration ensures stable control of complex valve geometries. The resolution of >4000 steps allows for microscopic adjustments, effectively eliminating hunting in sensitive loops. It is particularly robust in seismic-active zones, meeting DIN/IEC 68-3-3 Class III requirements.

Professional FAQ
How does the Fail Safe function operate in this double-acting model?
Upon loss of electrical power, the V18345-2010420001 vents the pneumatic output to move the actuator to a pre-defined safe position, ensuring process integrity.
What is the significance of the 20ms sample rate?
This high-speed sampling allows the positioner to react almost instantly to process fluctuations, significantly reducing the “dead time” of the control loop.
Can this unit be mounted on both linear and rotary actuators?
Yes, the aluminum case is pre-drilled for DIN/IEC 534 (linear) and VDI/VDE 3845 (rotary) standard mounting kits.
What air quality is required for long-term reliability?
You must use instrument air free of oil and water, specifically meeting ISO 8573-1 Class 3 purity standards to prevent clogging the sensitive nozzle-flapper system.
Selection Guide: Is the V18345-2010420001 right for high-vibration areas?
Yes, this model features an exceptionally low vibration influence (< 1% at 10g). It is the ideal selection for compressors or pipelines near high-frequency rotating equipment.
