Siemens actuators fall into the following categories:
(1) Control valves and actuators for central air conditioning;
(2) Valve actuators for room and area control;
(3) Solenoid control valves and actuators for cooling, refrigeration, central air conditioning and industrial applications;
(4) Damper actuator.
Damper actuators
Electric selector damper actuator GMA with spring return, GLB series valve actuator.
Siemens' comprehensive portfolio of damper actuators can be tailored to the user's specific HVAC requirements in terms of positioning forces, control signals, communication standards, and additional options. OpenAir actuators offer reliability and high efficiency for use with low-power motors for fast, precise function control. Both on the construction site and during operation, they achieve a long service life, significantly reduced energy consumption and durability.
Energy saving, easy to use and reliable: The entire damper actuator product line is very simple and efficient to use, easy to install, fast to commission and easy to operate. Standardized wiring diagrams and automatic centering fittings save time and money.
Easy to customize to specific requirements, damper actuators are reliable and durable to meet a wide range of application needs: ventilation comfort, variable air volume, fire and smoke dampers, railway vehicles and other special application requirements, as well as positioning forces, communication buses, control signals, etc.
Siemens Building Technologies offers energy-efficient and safe building and infrastructure solutions.
Siemens actuator applications: For applications where high thrust and safety are important, long-stroke valves for use with electro-hydraulic actuators are a good choice. Electro-hydraulic actuators are the choice for demanding district heating applications and large equipment. Their positioning, robustness, spring return agility and many other features are outstanding. Electro-hydraulic actuators are ideal for sub-circuit control in machine rooms and high-flow systems.
Advantages of Siemens electro-hydraulic actuator: (1) large thrust, suitable for large flow and large pressure difference; (2) Safe and reliable, even under very harsh conditions, it can ensure safe and reliable operation; (3) Economic use, solid structure, long service life.
The Siemens controller can automatically challenge the water flow in the primary side valve according to the outlet water temperature on the secondary side to achieve the effect of comfort and energy saving. The outlet water temperature of the heat exchanger compensates for changes according to the outdoor temperature, and the user feels comfortable during use, avoiding the strange circle that the higher the outdoor temperature, the higher the indoor temperature, the lower the outdoor temperature, and the lower the indoor temperature. Under the premise of comfortable use, users can save operating costs, reduce operating costs, and achieve considerable economic benefits.
Siemens actuator action principle: (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 down. The stem shrinks and the valve opens. At the same time, the return spring is compressed. (2) Close the valve: Start the electric valve to make the hydraulic oil in the pressure chamber flow back to the oil storage chamber, and the compressed spring pushes the pressure cylinder stem upwards and the valve is closed.
