Expert Review – Manager’s Insight

Why choose TZIDC V18345? This positioner gives precise control with very low air use. The aluminum housing stands tough conditions. Setup is easy with the local panel. The 20-point curve fits any valve. For critical processes, the shut-off function adds safety. Reliable, simple, and built to last.

Application Scenarios

• Control valves – linear or rotary, in oil & gas, chemical, power
• Dampers & louvers – HVAC and air handling systems
• Pneumatic actuators – single acting with fail-safe
• Remote locations – wide temp range and NEMA 4X protection

Frequently Asked Questions (FAQ)

• Q: What is the minimum input signal for this positioner?

  A: 4 mA. Split-range can start from 3.2 mA (20% of range).

• Q: Can I use this positioner in very cold environments?

  A: Yes, it works from -40°C up to +85°C.

• Q: What is the fail-safe position on power loss?

  A: The single-acting output drives to the fail-safe position (spring return).

• Q: How do I change the characteristic curve?

  A: Use the local panel or software to select linear, equal %, or define 20 points.

• Q: Does this positioner support NPT air connections?

  A: Yes, the model code “2” includes 1/4-18 NPT for air and 1/2-14 NPT for cable.
