VALPES Electric Actuator with Positioner and Emergency Function

The POSI-BBPR configuration integrates analog position control with battery-powered fail-safe return. It is used with electric actuators rated 25–2400 Nm for quarter-turn valves or multiturn applications, where both modulating control and a predefined fail position are required in case of power loss.

Compatible Series

  • VR / VS
  • VRX / VSX ATEX
  • DV / DVX DNV-GL and ATEX
  • VT PLUS
  • MT multiturn

Control Operation

The positioner accepts 4–20 mA or 0–10 V input signals and modulates the valve to intermediate positions. Feedback is available as 4–20 mA or 0–10 V, with signal inversion (e.g., 20–4 mA) possible. The BBPR function moves the valve to a preset position (normally open or normally closed) upon loss of supply voltage.

Technical Specifications

  • Duty rating: S4 50% per IEC34
  • Operating temperature: -10 to +40 °C
  • Enclosure: up to IP68, 10 m / 72 h (varies by series)
  • 4 adjustable limit switches, 5 A
  • Multivoltage supply
  • Manual override via handwheel or output shaft
  • Anti-condensation heater
  • Electronic torque limiter
  • Fault indication relay
  • AXMART Bluetooth for configuration, monitoring, and control

Applications

Used for control, filling, mixing, by-pass, and safety isolation valves where analog operation is required but a defined fail position is necessary during power outage. Media compatibility is determined by the valve; actuator selection depends on torque, control signal, fail position, enclosure rating, and ambient temperature.

FAQ

When is POSI-BBPR selected over standard POSI?
When loss of power must drive the valve to a specific fail position rather than leaving it at last position.

What is checked during maintenance?
Battery condition, setpoint/feedback signal, limit switches, fault relay, cable gland sealing, manual override function, and correct torque relative to valve requirements.
