Thermal actuator TWA-Q 230V NC (valve drive ABQ-M) with 1.2m cable 082F1600

Thermal actuator for valves – reliable flow control

The TWA-Q 230V NC thermal actuator is an actuator designed to work with ABQ-M valves, enabling smooth and precise regulation of the flow of hot or cold water in heating and cooling systems. This is particularly useful in installations supplying fan coil units, small heaters or coolers. Thanks to its design and principle of operation, the actuator provides effective control in systems maintaining a constant temperature.

Construction and application

The actuator uses the principle of thermal expansion to move the valve stem. The normally closed (NC) version is characterized by an extended stem in the rest state, which blocks the flow of medium. Upon receiving a control signal, the stem retracts, opening the valve. The opening or closing time is approximately 1.5 minutes, which ensures a smooth change in operating state. The 1.2 meter long cable facilitates connection to the controller.

Key features and benefits

• Versatility: Designed to work with ABQ-M DN10-32 valves, ensuring compatibility with a wide range of installations.
• Efficiency: Control using a simple on/off switch allows for easy integration with existing automation systems.
• Durability: The housing with an IP54 protection class protects against the influence of external factors, such as moisture and dust.
• Safety: Maximum water temperature up to 95°C allows use in most standard heating installations.
• Reliability: The construction based on proven thermal expansion technology guarantees long-term and trouble-free operation.
• Compact dimensions and low weight (0.20 kg): Facilitate installation even in tight spaces.
• Fast response: Opening/closing time of approx. 1.5 minutes ensures dynamic flow control.

This actuator is not only an automation element – it is a guarantee of precise temperature control and comfort in every heating or cooling system. It is also a practical solution for installers looking for a reliable and easy-to-install component.
