Product Description

AGM23 for QRA53/55 cables


Siemens actuators are divided into the following categories:

(1) Regulating valve and actuator for central air conditioner;

(2) Valve actuators for room and area control;

(3) Solenoid control valves and actuators for cooling, refrigeration, central air conditioning and industrial applications;

(4) Air valve actuator.

Air valve actuator

Electric selector valve actuator with spring return GMA, GLB series valve actuator.

The wind valve actuator product line of Siemens * * * can be customized according to the specific HVAC requirements of users in terms of positioning force, control signal, communication standard and additional options. The OpenAir actuator has good reliability, * * *, and can be used with low-power motors to realize fast and * * * function control. Both at the construction site and during the operation period, it can achieve long service life, significant reduction in energy consumption and 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. Standardized wiring diagram and automatic centering shaft connector are used to save * * * time and * * *.

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

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

Application field of Siemens actuators: For those applications that focus on high thrust and safety, the long-travel valve used in combination with electro-hydraulic actuators is undoubtedly a good choice. Electro-hydraulic actuator is the choice of strict regional heating application and large equipment. Their positioning force, firmness, agility of spring return and many other functions have * * * performance. Electro-hydraulic actuator is the ideal choice for the control of machine room and large flow system sub-circuit.

 

Siemens electrohydraulic actuator * *: ① large thrust, suitable for large flow and large differential pressure; ② It is safe and reliable, and can ensure operation even under very bad conditions * *; ③ Economical use, solid structure and long service life.
 

Siemens controller can automatically challenge the water flow in the valve at the primary side according to the outlet water temperature at the secondary side to achieve the effect of comfort and energy saving. The water outlet temperature of the heat exchanger is compensated according to the outdoor temperature. Users feel comfortable during use, avoiding the strange circle that the higher the outdoor temperature is, the higher the indoor temperature is, and the lower the outdoor temperature is, the lower the indoor temperature is. Under the premise of comfortable use, users can save operating costs, reduce operation costs and achieve considerable economic benefits.


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 downward. The valve rod retracts 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. The compressed spring pushes the valve rod of the pressure cylinder upward to extend, and the valve closes.
