Siemens' comprehensive product line of wind valve actuators can be customized according to the specific HVAC requirements of users in terms of positioning force, control signal, communication standards, and additional options. The OpenAir actuator has good reliability and high efficiency, and can be used in conjunction with low-power motors to achieve fast and accurate functional control. Whether on the construction site or during operation, it can achieve long service life, significantly reduced energy consumption, and long-lasting durability.

Energy saving, easy to use, and reliable: The entire air valve actuator product line is very simple and efficient to use, easy to install, fast to debug, and easy to operate. Adopting standardized wiring diagrams and automatic centering shaft connectors significantly saves time and costs.

The air valve actuator is easy to customize according to specific requirements, reliable and durable, and can meet various application requirements: ventilation comfort, variable air volume, fire and smoke prevention air valves, railway vehicles, and other special application requirements, as well as positioning force, communication bus, control signal, and other requirements.

Siemens Building Technology can provide energy-saving and safe building and infrastructure solutions.

Siemens actuator application field: For applications that prioritize high thrust and safety, long travel valves used in conjunction with electric hydraulic actuators are undoubtedly a good choice. Electric hydraulic actuators are the choice for demanding regional heating applications and large-scale equipment. Their positioning force, robustness, agility of spring return, and many other functions have excellent performance. Electric hydraulic actuators are the ideal choice for control of sub circuits in computer rooms and high flow systems.

The advantages of Siemens electric hydraulic actuators include: ① high thrust, suitable for high flow rate and large pressure difference; ② Safe and reliable, ensuring safe and reliable operation even under extremely harsh conditions; ③ Economical use, sturdy construction, and long service life.

The Siemens controller can automatically challenge the water flow rate inside the primary side valve based on the secondary side outlet temperature, achieving a comfortable and energy-saving effect. The outlet temperature of the heat exchanger compensates for changes based on the outdoor temperature. Users feel comfortable during use, avoiding the strange cycle of higher outdoor temperature, higher indoor temperature, and lower outdoor temperature. Users can save operating costs, reduce operating costs, and achieve significant economic benefits while using comfortably.

The action principle of Siemens actuator: ① Open the valve: The hydraulic pump pushes the hydraulic oil in the oil storage chamber to flow into the pressure chamber, so the pressure cylinder is used to move downwards. The valve stem contracts and the valve opens. At the same time, the return spring is compressed Close the valve: Activating the electric valve allows hydraulic oil in the pressure chamber to flow back to the oil storage chamber. The compressed spring pushes the pressure cylinder stem upwards and extends, causing the valve to close.
