Key Features

• High‑Precision Positioning: Microprocessor control with TEIP11 core technology delivers ±0.1% full‑scale accuracy and fast response for precise valve regulation.
• Fail‑Freeze Safety Function: Single‑acting design with “three‑break protection” locks valve position on loss of power, air supply, or control signal, ensuring process safety.
• Built‑In Analog Feedback: Integrated 4–20 mA position feedback eliminates need for external transmitters, simplifying system integration.
• Advanced Communication: Supports HART, Profibus PA, and Foundation Fieldbus for remote parameter configuration, real‑time monitoring, and predictive maintenance.
• Auto‑Commissioning: One‑button auto‑stroke setup automatically calibrates zero and span, reducing installation time and effort.
• Robust Environmental Design: IP65 enclosure, wide temperature range (-40°C to +85°C), and high vibration resistance (10g) for reliable operation in harsh conditions.
• Modular Construction: Compact, modular design enables easy maintenance, component replacement, and field upgrades.
• Local Operator Interface: Two‑line LCD and mechanical position indicator allow on‑site configuration and status monitoring without additional tools.
• Low Air Consumption: Optimized pneumatic design minimizes air usage (≤ 0.03 kg/h), reducing operational costs.
• Adaptive Control Algorithms: Built‑in temperature and position compensation maintains performance across varying operating conditions.
• Diagnostic Capabilities: Onboard self‑diagnostics monitor valve health, detect faults, and generate alarms for proactive maintenance.
