The Beok RZ-AN230-NO thermal actuator is a small control valve used in water-based underfloor heating systems, typically installed on each circuit of a manifold. The electric actuator opens and closes based on signals from a controller, regulating the circulation of hot water in the floor heating pipes to achieve indoor temperature control. In addition to its classic design, this electric actuator uses a French imported valve core to extend its service life. Although there are many products on the market with a similar appearance, our quality is superior.

This electric actuator is a normally open valve, which means that it remains open when there is no current. With the help of an indicator element, the actuator's status can be quickly checked. Therefore, this electric actuator is suitable for most underfloor heating water systems.

1. Q: Can a single thermal actuator control multiple heating zones?

   A: No, most thermal actuators are designed to control one valve (and thus one zone) at a time. For multi-zone systems, you’ll need one actuator per zone/valve, paired with a central control hub or multiple thermostats. This ensures each zone’s temperature is adjusted independently without cross-interference.

2. Q: What is the role of a 230V normally opend thermal actuator in a heating system?

    A: It is a valve component that stays open (allowing heat to pass through) when power is off and closes (cutting off the heat flow) when powered. It is a key component for zoning control in underfloor heating or radiator systems, allowing you to individually switch each zone through a thermostat.

3. Q: What causes a 230V normally opend thermal actuator to fail to open/close?

    A: Common issues include power supply problems (check voltage and wiring), a stuck valve mechanism (due to dirt or debris in the pipe), or a faulty coil. First, test the power; if that’s fine, remove the actuator to check for blockages or replace the coil if needed.

4. Q: How long is the product warranty period?

    A: Our products come with a 2-year free warranty. If there is a quality issue (such as failure to turn on or unresponsive buttons) after you receive the goods, you can contact the after-sales customer service and provide the order number and photos of the problem. We will arrange for a replacement or repair.
