Thermoelectric Actuator Afriso TSA 01, GW M30x1.5 mm, 230 VAC, NC

Afriso TSA 01 is a thermoelectric actuator designed to provide electrically driven linear motion for valve control in residential and commercial heating systems. With a GW M30x1.5 mm threaded connection and 230 VAC power supply, this normally closed (NC) actuator is intended for use on radiator valves and heating circuit valves where automatic flow regulation and reliable fail-safe closing are required.

Advantages

The actuator offers compact dimensions and a standard GW M30x1.5 mm thread for straightforward mounting on compatible valves. Its 230 VAC operation integrates easily into existing mains-powered HVAC installations without the need for additional transformers. The normally closed configuration ensures valves return to the closed position in the absence of power, supporting system safety and predictable behaviour. The unit is engineered for linear, repeatable stroke control suitable for modulating flow in heating circuits.

Suitable for

• Radiator valves in residential and commercial buildings
• Heating circuit zone valves and distribution manifolds
• Retrofit automation of thermostatic or motorized valve bodies with M30x1.5 mm connection
• Systems requiring mains-powered actuators with fail-safe closed position

Key specifications

• Mounting connection: GW M30×1.5 mm threaded interface
• Supply voltage: 230 VAC mains operation
• Operational mode: Normally closed (NC) – closes when unpowered
• Actuation type: Thermoelectric, linear stroke output for valve actuation
• Application area: Designed for radiator and heating circuit valve control in HVAC systems

How to use

Mount the actuator onto a compatible valve body with a GW M30x1.5 mm threaded connection, ensuring correct mechanical engagement and secure fastening. Connect the supply to a 230 VAC source following local electrical codes and observe polarity and grounding requirements where applicable. During operation the thermoelectric element will drive linear motion to open the valve when powered; upon power loss the actuator returns to the closed position. Verify travel and alignment after installation and perform functional tests with the HVAC control system to ensure correct response.

Usage recommendations

Install the actuator in dry, accessible locations and protect electrical connections from moisture. Confirm compatibility with the specific valve body and HVAC controller before installation. Periodically inspect mounting and wiring for secure condition and perform functional checks to maintain reliable operation.
