Expert FAQ & Selection Guide

• Question: What happens to the valve position if the 4-20mA signal is lost?
  Answer: Since the V18345-1010120001 is a “Fail-Safe” model, the pneumatic output will bleed, allowing the actuator spring to move the valve to its mechanical safe position.
• Question: Is this positioner compatible with M20 conduit threads?
  Answer: No, this specific model (V18345-1010120001) uses 1/2-14 NPT electrical entries. Ensure your conduit fittings match this standard.
• Question: How does the “Shut-off” function protect the valve seat?
  Answer: You can configure a limit (e.g., 1%) where the positioner applies full air pressure to ensure the valve is tightly closed, preventing seat erosion.
• Question: What is the benefit of the LKS adapter plug in this model?
  Answer: It allows for rapid PC-based configuration and diagnostic software connection without opening the main housing.
• Question: Selection Guide: Why choose the NPT connection variant over G threads?
  Answer: The V18345-1010120001 (NPT) is the preferred standard for North American projects and heavy industrial sites using NPT-threaded instrumentation tubing for better sealing in high-pressure environments.
