VALPES Electric Actuator with Emergency Function

The emergency function / BBPR utilizes a backup battery to return the valve to a predefined safe position upon loss of power supply. The fail-safe position can be configured as fail-close or fail-open, depending on process requirements and valve logic. This function is available on VALPES actuators rated from 10 to 2400 Nm.

Compatible Series

Emergency function is implemented in the following series: ER PLUS, VR/VS, VRX/VSX ATEX, DV/DVX DNV-GL & ATEX, VT PLUS, and MT multiturn. Suitable for quarter-turn valves (ball, butterfly, plug) and multiturn applications via the MT series.

Technical Specifications

  • Duty cycle: S4 50% per IEC34
  • BBPR operating temperature: -10 to +40 °C
  • Control: on-off
  • Integrated anti-condensation heater
  • Software torque limiter
  • Status/fault relay output
  • Manual override via handwheel or output shaft
  • 4 adjustable limit switches, 5 A
  • Multivoltage versions available
  • Ingress protection: IP66 to IP68 10 m / 72 h (series dependent)

Control and Configuration

GS6 models include AXMART Bluetooth for battery charge monitoring, system status, and safe position adjustment. Battery supply disconnects after 2 minutes to minimize discharge. Functionality can be combined with POSI, 3-position, or Modbus-RTU in compatible versions.

Applications

Applicable in water lines, air, HVAC, water treatment, marine piping, auxiliary gases, and Ex environments (with ATEX series). Media compatibility is determined by the valve; actuator selection is based on torque, voltage, 90° cycle time, IP rating, fail-safe position, and duty cycle.

FAQ

When is emergency function required?
When the valve must move to a safe position upon loss of electrical supply.

What is checked during maintenance?
Battery condition, charge cycle, fault relay, limit switches, cable glands, IP sealing, manual override, and correct torque matching to the valve.
