What Are Valves & Actuators
Valves regulate heat, cooling, steam or chilled water in HVAC systems – while actuators precisely open, close or modulate that flow. Together, valves and actuators deliver accurate temperature control, energy efficiency, and automation.
Siemens Acvatix valves and OpenAir actuators are engineered for smart building integration, enabling fast commissioning, automated hydronic balancing, and seamless BMS connectivity.
Optimised HVAC Performance
Ensure stable temperatures and comfort with precise flow control. PICV and Intelligent Valves automatically balance hydronic systems for consistent HVAC performance.
Fast, Reliable Installation & Commissioning
Combi Valve Sizer and HIT tools simplify product selection and BIM integration. Actuators install easily with colour-coded connectors and bayonet mounts.
High Control Accuracy & Energy Savings
Modulating and on/off actuators enable accurate stroke control. Dynamic valves prevent overflows and oversizing, reducing energy consumption by up to 25%.
Seamless Smart Building Integration
Actuators support wireless setup via ABT Go or cloud, ideal for BMS-ready HVAC automation and smart metering ecosystems.
Ball, Globe & Butterfly Control Valves (Acvatix Series)
Siemens Acvatix includes ball valves, globe valves, and butterfly valves designed for robust hydronic systems in heating, cooling, or mixed energy applications.
Key Points:
High precision ball valves for leak free, stable HVAC control
Globe valves for flow regulation and mixing duties
Butterfly valves for large-volume, low-pressure HVAC applications like chillers or cooling towers
Magnetic valves for quick shutoff and mixing in hydronic circuits
Pressure Independent Control Valves (PICV) for automatic balancing and energy-efficient system modulation
Intelligent & Magnetic Valves
Includes Siemens Intelligent Valves and integrated magnetic valve actuators.
Key Points:
Intelligent Valves self-optimise flow control with preset commissioning and WLAN setup
Delivers reduced operating costs and consistent comfort
Ideal for use in heating groups, AHUs, fan coil units, and VAV zones
Rotary, Damper & Valve Actuators (OpenAir™)
Siemens OpenAir™ actuators offer a broad range of torque ratings and control modes for valves and dampers.
Key Points:
Rotary actuators for modulating valve and damper control (0–10 V, floating)
Damper actuators, including spring return, fail-safe, and fast-acting models, ideal for VAV and economizer control
Valve actuators designed for ball, globe, PICV and butterfly valves with direct coupling
Options include electromotronic, electrohydraulic, and power-efficient models for long life and robust HVAC control
Pressure Independent Control Valves (PICV)
Siemens PICVs integrate three critical functions – control valve, adjustable flow limiter, and automatic pressure regulator – into a single device, enhancing system performance and optimising ΔT. These valves maintain full stroke, minimise actuator hunting, and enable rapid on-site commissioning with maximum flow presets and auto-balancing.
Key Points:
Built-in differential pressure regulation delivers constant volumetric flow, ensuring accurate temperature control and improved occupant comfort across varying load conditions.
Reduces energy waste by preventing hydronic overflow or undersupply and maintains ΔT, supporting energy-efficient HVAC operation and operational cost savings.
