Features

① Multiple Explosion-proof Options

• Intrinsically Safe (Ex ia IIC T6 Ga): Suitable for Zone 0/1/2 hazardous areas, with no ignition risk under normal or fault conditions.

• Flameproof (Ex d IIC T6 Gb): Suitable for Zone 1/2 hazardous areas, featuring an aluminum alloy flameproof enclosure with a flame path design.

• Certified by ATEX, IECEx, and GB 3836, meeting global hazardous area standards.

② High Ingress Protection

• Standard IP66 protection (dust-tight, protection against powerful water jets from any direction), optional IP67 protection, fully resisting the intrusion of outdoor dust and high-pressure flushing water, suitable for humid and dusty plant environments.

③ High-Precision Smart Control

• One-touch auto-calibration: Automatically identifies actuator stroke, action mode (air-to-open/air-to-close), and friction, completing quick commissioning within 3 minutes without complex operations by professional personnel.

• Positioning accuracy ≤ ±0.5% F.S., hysteresis ≤ 0.5%, dead band ≤ 0.1%, ensuring stable regulation of process flow, pressure, and liquid level.

• Configurable flow characteristics: One-click switching between Linear, Equal Percentage, and Quick Opening via local buttons or HART communication, no cam replacement required, adapting to different process curve needs.

④ Efficient Pneumatic System

• Equipped with a piezoelectric pilot valve, with a response speed of millisecond level, suitable for large-thrust and large-diameter actuators; extremely low steady-state air consumption (≤36 L/h), achieving energy saving and consumption reduction during long-term operation.

• Supply pressure range: 0.14–0.7 MPa (14–70 psi), output pressure: 0.2–0.7 MPa (3–100 psi), compatible with most industrial pneumatic actuators.

⑤ Operation and Safety Design

• Local cover-free operation: LCD display + 3 physical buttons, enabling parameter calibration and fault checking without opening the explosion-proof enclosure, ensuring safer operation in hazardous areas.

• HART 7.0 communication: Standard 4–20 mA two-wire input + HART remote communication, supporting remote parameter setting and equipment monitoring, improving operation and maintenance efficiency.

• Fault safety protection: Supports three fault modes (hold, full open, full close) in case of air or power failure, which can be configured on demand to ensure the safety and stability of the process system.
