RZ-AV 4 Wire Thermal Actuator For Smart Heating Control

Shanghai Beok Controls Co., Ltd. is one of the most reliable manufacturers and suppliers of rz-av 4 wire thermal actuator for smart heating control in China. Our factory offers high quality products made in China with competitive price. Welcome to contact us for free sample and cheap products.

In modern HVAC and underfloor heating systems, precise temperature regulation is essential for comfort, efficiency, and energy savings. BEOK 4 wire thermal actuator is designed to deliver reliable valve control performance for residential and commercial heating applications. Built with advanced thermal expansion technology and durable materials, this actuator ensures stable operation, fast response, and long service life in various hydronic heating environments.

This 4 wire electronic actuator is an electrothermal device used to open or close valves in heating and cooling systems. It converts electrical energy into mechanical movement through a heated wax or thermal element, allowing accurate flow regulation in manifolds, radiators, fan coil units, and zone valves.

Compared with standard two-wire actuators, the four-wire design provides additional signal or auxiliary connection options, making it suitable for intelligent HVAC control systems and smart thermostatic applications.

Key Features of the 4 Wire Thermal Actuator

 

 

Reliable Thermal Drive Technology

The actuator uses a high-quality thermal expansion mechanism to ensure smooth and silent operation. Once powered, the internal heating element activates the expansion medium, driving the valve stem accurately.

 

Universal M30×1.5 Connection

Designed with a standard M30×1.5 threaded connection, the actuator is compatible with most manifold valves and hydronic control systems available on the market.

 

Energy-Efficient Performance

Operating at low power consumption, the actuator helps reduce overall energy usage while maintaining stable room temperature control.

 

 

Applications of the 4 Wire Thermal Actuator

The BEOK actuator is widely used in:

• Underfloor heating systems
• Hydronic heating manifolds
• Smart home HVAC solutions
• Radiator valve control
• Fan coil units
• Commercial heating automation
• Zone control systems

Whether for residential apartments, office buildings, hotels, or industrial facilities, this actuator provides dependable valve control for modern heating infrastructure.
