GA-184U

Hydraulic flow control through GA-184U

In operation, the GA-184U responds to voltage applied to its electromagnet. The internal valve mechanism changes position and opens or closes the hydraulic passage according to the system layout. When power is removed, the valve returns to its normal state as defined by the installation. This type of unit is used where hydraulic flow needs to be controlled from the aircraft electrical system, for example in actuator circuits, landing gear related lines, braking circuits, or other hydraulic functions where the aircraft documentation specifies this valve.

GA-184U in actuator and service hydraulic circuits

Inside the hydraulic system, GA-184U works together with pressure lines, return lines, fittings, actuators, control switches, wiring, and the hydraulic fluid supply. If the connected mechanism does not operate, the valve is only one possible cause. Maintenance checks normally include electrical power at the connector, electromagnet operation, valve movement, pressure in the line, leakage, fluid cleanliness, and the condition of the actuator. A problem in any of these areas can look like a valve fault.

Aircraft application of hydraulic valve GA-184U

The GA-184U is used in aircraft hydraulic systems, with open catalog references confirming application on Mi-26 helicopters. Other supply lists may show the valve in aircraft spare parts stock or near related electromagnetic hydraulic valves from the GA series, but exact applicability should be checked by the aircraft parts catalog. A similar valve from the same family may not match the required installation if the version, port layout, operating logic, or acceptance documentation differs.

Identification and ordering checks for GA-184U

Before ordering, the marking on the installed valve should be compared with the aircraft parts catalog, product passport, or technical conditions. The product may appear as GA-184U in English-language documents and as ГА-184У in Russian documentation. The related version GA-184U/2 / ГА-184У/2 may appear in separate references, but interchangeability must be confirmed by documentation. A clear request should include the aircraft type, system location, full designation, and a photo of the marking if available. The product is also known under alternative designation ГА-184У.
