York 025-47580-000 Actuator 025-38178-000

The York 025-47580-000 025-38178-000 throttle orifice plate motor actuator is specially designed for York centrifugal chiller units. It is mainly applied in the throttling regulation section of the chiller's main refrigerant circuit, installed at the inlet throttle orifice plate drive mechanism of the evaporator. It is the core executive component of the chiller's capacity regulation system.

Its core application scenarios cover three categories: First, variable load operation regulation scenarios. When the chiller units in commercial buildings, industrial plants, data centers, etc. are operating at partial load conditions, they receive instructions from the chiller controller to precisely adjust the opening degree of the throttle orifice plate, matching the refrigerant flow with the actual cooling demand, optimizing the operating energy efficiency of the chiller, and reducing operating energy consumption. Second, start-stop and operation mode switching control scenarios. During the startup, shutdown, and significant load fluctuations of the chiller units, precise flow control is adopted to avoid risks such as compressor cavitation and sudden changes in system pressure, ensuring a smooth transition of operating conditions. Third, after-sales maintenance and replacement scenarios. When the original actuator experiences action stalling, positioning deviation, or motor failure, it can be directly replaced with the same model of old parts, without modification, and quickly restore the chiller's flow regulation function.

This actuator is compatible with York's mainstream centrifugal chiller unit series. It can withstand the low-temperature, oil contamination, and continuous vibration operating environment of the refrigeration room. At the same time, it is suitable for scenarios such as original factory matching, fault repair, and annual preventive major maintenance of the chiller units.
