Expert Review
- Manager’s Insight: “The TZIDC is a workhorse for critical valve control. Its modular design and multiple certifications make it versatile for oil, gas, and chemical plants. The analog feedback option simplifies integration with existing DCS. For harsh environments, the aluminium housing and wide temperature range are clear advantages.”
Applications
- Control valves in refineries
- Gas turbines and compressors
- Chemical reactor feed lines
- Power plant steam systems
- Water treatment – large butterfly valves

Frequently Asked Questions
- What is the difference between fail‑safe and double acting?
Fail‑safe moves the actuator to a safe position when power is lost. Double acting means air is applied to both sides of the piston. - Can I use this positioner in Zone 0?
No. It is certified for Zone 1 (II 2G) and Zone 2 (II 3G), not Zone 0. - Is the analog feedback module pre‑installed?
Yes, this model includes the 4‑20 mA feedback plug‑in module (option code 1). - What air quality is required?
Use dry, oil‑free instrument air per ISO 8573‑1, class 2 or better. - How do I mount it to a rotary actuator?
Use the VDI/VDE 3845 mounting kit (available separately).
Selection Guide
- Check your actuator type – linear or rotary.
- Define the required fail‑safe action (single/double acting).
- Choose analog feedback if you need a 4‑20 mA position signal.
- Select explosion protection based on zone classification.
- Verify ambient temperature range matches your site.
