Electric Linear Actuator ARI-PACO 0.85 D/Y

The ARI-PACO 0.85 kN is an electric thrust actuator designed for small linear control or shut-off valves, with a nominal force of 0.85 kN and a maximum stroke of 20 mm. It is primarily used in HVAC valves, hot/cold water circuits, and auxiliary process loops where limited seating force and short actuator travel are required.

Control Versions

• ARI-PACO 0.85 D: 3-point control, 230 V AC 50/60 Hz supply, 4.1 VA power consumption.
• ARI-PACO 0.85 Y: Analog input 0–10 V or 2–10 V DC, reversible, with 0–10 V DC position feedback.
• Stroke speed: 0.11 mm/s.
• Duty cycle: S3 50% ED.
• Protection class: IP54 (DIN VDE 0470).
• Ambient temperature: 0 to +50 °C.

Mechanical Operation

End position cut-off is torque/thrust-based to prevent uncontrolled stem overload. Manual override wheel, stroke indicator, stem coupling, and shaft protection cover are included. Installation is permitted from horizontal up to vertical above the valve body.

Features of PACO 0.85 Y

The Y version provides automatic stroke adaptation during initialization, selectable control/feedback direction, operation status LED, dynamic hysteresis for signal interference rejection, and valve anti-blocking with periodic movement if the valve remains closed for 24 hours.

Accessories

Available options include 1000 Ω potentiometer, additional limit switches for D version, and switch board for Y version with two dry changeover contacts (3 A / 250 V AC) for position indication or fault signaling to automation panels.

FAQ

When to select the D version?
Use when the controller provides open/close commands via 3-point control.

When to select the Y version?
Use when analog position control and 0–10 V feedback to BMS or PLC is required.
