Thermoelectric Actuator SALUS RT30NC M30 x 1.5 230 V

The Thermoelectric Actuator SALUS RT30NC M30 x 1.5 230 V is a thermoelectric valve actuator designed for controlling radiator and valve systems in zonal heating applications. As a normally closed (NC) device, it converts electrical input into linear mechanical movement to open valves when powered and close them when power is removed. The actuator features an M30 x 1.5 mounting thread and is intended for use with 230 V mains supply, providing straightforward integration into central heating and HVAC systems that require motorized control of fluid flow.

Advantages

The actuator offers compact dimensions and a standardized M30 x 1.5 mounting interface that simplify installation on compatible valves. Its NC operation ensures valves remain closed in the absence of power, supporting fail-safe behavior for many heating zone designs. Operating from a 230 V supply eliminates the need for additional transformers in installations with mains power available, and the electromechanical design delivers reliable linear motion for accurate valve positioning over repeated cycles.

Suitable for

• Radiator valve automation in central heating systems
• Zonal temperature control in residential and light commercial HVAC
• Replacement or retrofit of manual valve actuators with motorized control
• Systems requiring normally closed fail-safe valve behavior

Key specifications

• Mounting thread: M30 x 1.5
• Operating mode: Normally closed (NC)
• Supply voltage: 230 V AC
• Actuation type: Thermoelectric / linear movement
• Intended application: Radiator and valve systems for zonal control

How to use

Install the actuator onto a compatible valve using the M30 x 1.5 thread, ensuring the valve stem and actuator coupling are clean and properly aligned. Connect the actuator to a 230 V mains supply following local electrical codes and safety practices; wiring should be performed by a qualified technician. After mounting and power connection, test the actuator operation by applying and removing mains power to verify that the valve opens when powered and closes when power is removed. Integrate the actuator with thermostatic controllers, zone valves, or building management systems as required for automated or remote control.

Usage recommendations

Use the actuator in dry, indoor environments and avoid exposure to direct water or corrosive atmospheres. Verify compatibility with the specific valve body before installation and follow recommended torque and mounting instructions from the valve manufacturer. For safety and compliance, have electrical connections made by a qualified electrician and ensure the supply voltage matches the actuator rating.
