Features:
- Provides variable-speed electric actuation for ON-OFF valve duty.
- Uses the 2SA7031 size with a documented 37–125 Nm tripping-torque class.
- Combines ECOTRON controls with the selected relay-board extension and local operation.
Use the full 2SA7031-0CE20-3BA code when matching the configuration defined by 37–125 Nm size with configured speed, voltage and ECOTRON control selections.
It applies variable-speed motor torque to a multi-turn valve while integrated electronics supervise travel, torque and command handling.
The replacement review must resolve flange, output shaft, speed, voltage or I/O assignment before the equipment is returned to service.
Availability is subject to Apter Power inventory and sourcing confirmation.

- The Class A ECOTRON multi-turn actuation configuration operates multi-turn gate, globe or similar industrial valves in Class A ON-OFF service.
- The Class A ECOTRON multi-turn actuation configuration provides variable-speed opening and closing with electronic torque limitation for valve protection.
- The Class A ECOTRON multi-turn actuation configuration integrates motorized valve commands and position feedback with a compatible plant control system.
- Valve travel is set by the installed mechanical turns and the configured travel-dependent cut-off points.
- The actuator torque class is adjustable over 37–125 Nm for the documented 2SA7031 size.
- Output speed and stem travel must remain within the valve and gearbox manufacturer's permissible range.
- The SEVEN actuator family is specified to IP68 when the enclosure, plug system and seals are assembled correctly.
- Standard corrosion protection corresponds to corrosivity category C5 for the documented enclosure system.
- Environmental performance depends on preserving cable sealing, coating integrity and any separate-electronics installation details.
- The actuator is designed for ON-OFF duty in class A according to the cited actuator standard.
- Variable output speed and adjustable tripping torque allow controlled valve opening and closing.
- OPEN, CLOSE and STOP commands are handled through the documented ECOTRON binary inputs.
