ST/K 1.2 Electromotor Valve Drive, featuring modern design and enhanced functionality, is an all-in-one actuator with integrated controller, integrated temperature sensor, and secure communication via KNX Data Secure that directly connects to the KNX bus. 

It delivers seamless installation and efficient heating and cooling control in KNX building automation. Whether you’re working on new installations or upgrades, this device simplifies planning and installation while ensuring reliable and efficient control of heating and cooling systems.   

Key features and benefits

One of the key features of the ST/K 1.2 is its integrated controller and temperature sensor, providing real-time monitoring and adjustments. Two binary inputs allow for flexible applications, making the device versatile and adaptable to different scenarios. Additionally, the device is universally compatible with a wide range of valve adaptors, making it suitable for various applications.

With a high actuating force of up to 220 N and a maximum valve stroke of 8 mm, reliable operation, even under high flow rates and pressure conditions is ensured.  

It has a direct connection to the KNX bus system. This eliminates the need for a separate KNX Valve Drive Actuator, streamlining the installation process and reducing costs. The device is powered directly through the KNX system, ensuring seamless integration with your building’s automation infrastructure.
