Thermal actuator TWA-Q 24V NC (valve drive AB-QM), with 1.2m cable 082F1602

Thermal actuator for precise regulation

The TWA-Q 24V NC thermal actuator is a reliable device designed to control valves in heating and cooling systems. Its construction ensures smooth and precise flow control, which translates to optimal system performance. With a supply voltage of 24V, the actuator is compatible with a wide range of controllers and building automation systems.

Characteristics and application

The TWA-Q actuator in the normally closed (NC) version means that the valve remains closed in the event of a power failure. This solution is particularly useful in applications where safety is a priority – for example, in the event of a power failure, the system automatically goes into a safe state. A cable length of 1.2 meters ensures convenient installation and connection to the controller. The device is dedicated to cooperation with AB-QM valves with a diameter of DN 10-32.

• Precise regulation: Provides accurate flow control, allowing for maintaining optimal temperature in the room.
• Safety: Normally closed version guarantees automatic valve closure in case of power failure.
• Versatility: Compatible with various types of controllers and building automation systems thanks to the On/Off and PWM control signal.
• Durability: Made of high-quality materials, resistant to corrosion and mechanical damage, ensuring long device life.
• Protection: Protection class IP54 protects against dust and moisture, allowing installation in various environmental conditions.

Technical specifications and compliance with standards

The actuator meets the requirements of EC EN 60730 standard, which confirms its safety and reliability. The actuator stroke is 5 mm, which ensures effective valve opening and closing. The device has a REACH certificate regarding the content of hazardous substances (lead). The use of the TWA-Q actuator allows for the creation of an efficient and energy-saving heating or cooling system that meets the latest environmental standards.
