Siemens presents new state-of-the-art
actuator line for small valves

• Brings greater installation flexibility thanks to IP54 protection rating

• LED display for enhanced user experience

• New feedback signal for safety-critical applications

The new SSA actuators for small valves have been added to the Acvatix valve and
actuator line from Siemens Smart Infrastructure. They feature new functions that
transform the existing product portfolio and support hydronic room applications with
superior control accuracy, energy efficiency as well as reliability. The Acvatix
product line meets all control and hydronic requirements associated with the
generation, distribution and use of heating and cooling. The SSA actuators feature
quiet and fault-free operation and manual override for flexible valve and actuator
testing, regardless of system availability. New features offer a variety of installation
options as well as a choice of installation direction. With new functionalities such as
feedback signal for safety-critical applications and a modern, compact and IP54­compatible design, the new actuators can be used for more applications than ever.

Flexible, fast and space-saving installation

All new actuators are delivered pre-configured and are ready for immediate
installation. The newly introduced IP54 protection rating accommodates all
installation directions, including overhead installations, for even greater versatility. In
addition, the new products offer automatic hub adaptation, ensuring that every
valve-actuator combination is perfectly matched. Increased comfort and additional
energy-saving potential are achieved in combination with pressure-independent
control valves (PICVs). PICVs prevent oversupply and reciprocal hydronic
interference, ensuring a balanced hydronic system under all load conditions.

commissioning. It shows the position of the valve and different operating states and
helps users with various functions, such as self-calibration.

New features for customized applications

The actuators are particularly cost-efficient because they accommodate the needs
of users, allowing them to buy actuators with just the functions required for their
projects. Users can choose between a basic and a premium version with feedback
signal and manual adjustment. The feedback signal enables early fault detection
and fast elimination of inconsistencies, helping prevent system downtime. The
technology of the actuator is with <30 dB optimized for silent applications making it
one of the quietest products in this segment. This makes the new SSA actuators
ideal for use in hotels, hospitals and libraries. Since they are 100% backward­compatible, old actuators can easily be replaced during ongoing operations.
