YORK 025-38178-000 – ELECTRIC ACTUATOR
The York 025-38178-000 electric actuator is a genuine OEM control component from Johnson Controls–York, engineered to drive air dampers and chilled water valves in commercial and industrial HVAC systems within our chiller spare parts range, converting control signals from the equipment panel or BMS into precise rotary motion with 266 in-lb (approximately 30 N·m) of torque, running on 24 VAC at 7 VA directly off the existing control transformer with no auxiliary power needed, and completing a full 90° stroke in 120 to 135 seconds to prevent water hammer in hydronic circuits and pressure spikes in duct systems. Since chillers and air handling units in Saudi Arabia run at near-peak load for more than eight months a year, a single failed actuator means a damper frozen in position, lost air balance across zones, and rising electricity use with no gain in cooling capacity, making local availability of the genuine part the difference between a two-hour repair and a multi-week shutdown, and making it the right part for maintenance engineers at malls, hospitals, and hotels, O&M contractors on MEP agreements, and procurement officers at industrial facilities standardized on York equipment.
Key Features
- 100% genuine OEM part: factory York / Johnson Controls part number, not an aftermarket equivalent or a rebranded substitute.
- High 30 N·m torque output: drives dampers up to roughly 3 m² depending on blade type and duct static pressure.
- Non-spring-return design: holds last position on power loss, which is the correct behavior for mixing dampers and return air dampers.
- NEMA 2 enclosure with IP54 ingress protection: resists dust and splash, critical for open plant rooms and rooftop installations exposed to airborne dust.
- Wide operating range: −32 °C to +55 °C: handles summer plant room temperatures in Riyadh and Dammam without derating.
- UL listed and CE marked: documented compliance you can attach to project handover and technical submittal files.
- Direct shaft mounting: clamps straight onto the damper shaft, no external linkage required in most applications.
Benefits of Using This Actuator
Precise airflow control and zone balance: When the actuator tracks its control signal accurately, every zone reaches setpoint without overcooling, which shows up directly in occupant complaints and in your electricity bill.
Lower energy consumption: A damper stuck fully open forces the unit fan to run against continuous excess load. Restoring proper modulating control measurably reduces fan energy in variable air volume systems.
Extended compressor life: In chilled water valve applications, a functioning actuator prevents sudden full flow through the evaporator, reducing the short-cycling that wears compressors out early.
Preserved equipment warranty: Fitting non-genuine components inside a York unit still under warranty can void coverage on any related failure.
Reduced downtime: Local availability inside Saudi Arabia means repair in days rather than weeks waiting on international freight and customs clearance.

Frequently Asked Questions
Q1. Is the York 025-38178-000 a genuine or aftermarket part?
It is a genuine York OEM part from Johnson Controls, supplied new in factory packaging. It is not an aftermarket equivalent.
Q2. What torque does it deliver?
The actuator delivers 266 in-lb of torque, which is approximately 30 N·m.
Q3. What voltage does it require?
It requires 24 VAC at 50/60 Hz and has a power consumption of 7 VA.
Q4. Can it run on 220 V directly?
No. The actuator is designed for 24 VAC and must not be connected directly to 220 V, as this can cause immediate damage. It requires a 24 V control transformer, which is typically already installed in compatible York equipment panels.
Q5. How long does a full stroke take?
A full 90° rotation takes approximately 120 to 135 seconds.
