Siemens SUA21/3 Linear Valve Actuator
Precise, energy-efficient valve actuation for modern HVAC installations.
The Siemens SUA21/3 Linear Valve Actuator is a professional actuator engineered for precise flow control in industrial facilities. In addition, it automates valve opening and closing in HVAC systems with dependable on-off operation. Furthermore, its 170 Newton thrust ensures full compatibility with DN15, DN20 and DN25 valve bodies.
Powered by 230 V AC / 50 Hz, this actuator performs a complete stroke in 10 seconds, enabling rapid system flow control. Moreover, the on-off control principle optimizes energy use because the unit consumes no power in fully open or closed positions. In addition, a 2.5 mm stem diameter supports accurate positioning, while the 0.8 metre cable simplifies installation. The IP40 rating suits indoor applications, and the LED indicator visually confirms actuator movement.
