Thermoelectric Actuator Engo E30NC230 230V M30×1.5

Thermoelectric actuator Engo E30NC230 is a 230 V normally-closed (NC) linear actuator with an M30×1.5 threaded connection designed for automatic control of valves and HVAC dampers. It converts mains electrical input into controlled linear motion to drive valve stems or damper spindles, providing reliable on/off operation in heating, ventilation and air conditioning systems where electrically driven valve actuation at 230 V is required.

Advantages

The actuator provides simple on/off control with a normally closed position that ensures valves remain closed when power is removed. Its compact M30×1.5 threaded design allows straightforward mounting on compatible valve bodies and dampers. Operation at standard 230 V mains voltage eliminates the need for additional transformers in typical building installations. The device is intended for integration into automatic control circuits for building heating and ventilation systems, offering predictable linear stroke and repeatable performance for routine valve and damper actuation.

Suitable for

• Actuation of two-way and three-way valves in heating systems
• Control of HVAC dampers and air handling units
• Integration into building automation for zone control
• Replacement of manual valve actuators with electrically driven control

Key specifications

• Operating voltage: 230 V AC
• Actuation type: normally closed (NC)
• Thread connection: M30×1.5
• Motion: linear stroke to drive valve stem or damper spindle
• Intended application: valves and HVAC dampers

How to use

Mount the actuator on a compatible valve or damper with an M30×1.5 thread, ensuring correct mechanical engagement with the valve stem or spindle. Connect the actuator to a 230 V AC supply following local electrical regulations and wiring diagrams provided by the system designer. Control the actuator via a thermostat, relay, or building automation output; when energized the actuator will change from its normally closed position to operate the valve or damper. For safe installation and service, disconnect mains power before mounting, wiring or maintenance.

Usage recommendations

Use the Engo E30NC230 actuator in dry, indoor installations or within protective housings where exposure to moisture or corrosive environments is likely. Verify compatibility of stroke and torque with the target valve or damper before installation. Follow local electrical codes and manufacturer guidance for wiring and periodic inspection to ensure reliable operation.
