Products Description

RZ-AK230-NC 230V normally closed thermal actuator is designed for precise water flow control in hydronic underfloor heating systems. Engineered for reliability and long service life, this product is an essential underfloor heating actuator for manifold-based installations in residential, commercial, and light industrial applications.

Featuring a normally closed (NC) design, the valve remains closed when the RZ-AK actuator is not powered, ensuring safe operation and preventing unintended circulation. Powered by 230V AC, it provides stable and consistent performance across a wide range of heating control applications.

RZ-AK 230V normally close thermal actuator

Technical Design and Operating Performance

This thermal actuator works on a heat expansion principle, enabling smooth and silent valve actuation without mechanical vibration. Its low energy consumption supports efficient system operation while maintaining accurate response to thermostat signals.

As a professional underfloor heating actuator, it allows individual loop control on heating manifolds, supporting zoned temperature regulation when used with Beok Controls thermostats or other compatible controllers. The compact structure ensures easy installation even in tight manifold cabinets.

Manufactured with durable, heat-resistant materials, the actuator is designed for long-term operation with minimal maintenance, making it suitable for both new installations and retrofit projects.
