Bernard Controls AQL7 Electric Quarter-Turn Actuator

The AQL7 is an electric quarter-turn actuator designed for small isolation or basic modulating valves. In the AQL series technical documentation, it is referenced as AQ7L, alongside AQ1L and AQ3L, with a direct-mount torque range of 15–70 Nm.

Technical Specifications

  • Compatible with ball, butterfly, and plug valves.
  • Supports On-Off Class A or Inching / Positioning Class B operation per EN 15714-2.
  • DC motor, duty cycle S4-30%.
  • Up to 120 starts/hour at peak operation.
  • Ambient temperature range: -20 to +60 °C.
  • Enclosure: IP68 / NEMA 4X, corrosion protection C4 per ISO 12944.

Power Supply and Control

Standard supply: 1Ph 85–260 V AC, 50/60 Hz. Options for 24 V DC or 12 V DC (2- or 3-wire). SWITCH version is pre-wired. Available options include position transmitter 4–20 mA and positioner 4–20 mA in/out for modulating service.

Mechanical Interface and Indication

Valve mounting per ISO 5211. Limit setting via adjustable camblock and two SPDT open/close switches, plus two auxiliary signal switches. Manual override through 10 mm hex output.

Applications

Suitable for small water lines, air, HVAC, auxiliary gases, industrial utilities, and water treatment systems. Media compatibility is determined by the valve and its materials. Actuator selection is based on required torque, 90° operating time, voltage, duty cycle, and environmental conditions.

FAQ

When to select AQL7 over AQL1?
When the valve requires torque near the upper limit of the AQL series.

What is checked during maintenance?
Cable glands, IP sealing, camblock, auxiliary switches, ISO 5211 interface, position indication, and manual hex override.
