UE24/1-2

Operating principle of UE24/1-2

When the solenoid is energized, the hydraulic distributor connects the pressurized brake line to return and releases the wheel brake. After power is removed, the valve restores normal hydraulic supply to the brake circuit. Reliable operation depends on clean working fluid, the moving element, seat, springs and seals. Contamination, reversed connections or an unsuitable pressure can prevent the intended response.

Role in the aircraft system

Aircraft wheel-brake and anti-skid circuits. An-24/An-26/An-30 and Yak-40 technical documentation identifies UE24/1-family electrohydraulic valves in automatic braking or brake-release functions. The valve works with pipelines, a pressure source, downstream equipment and the control elements of its circuit. These products are functionally related but must not be described as interchangeable merely because they operate in the same system.

Installation and maintenance checks

Before installation, verify the nameplate, ports, flow direction, internal cleanliness and seal condition. Working pressure, temperature, fluid and the prescribed functional test must come from the passport and maintenance documentation. Adjustment without approved instructions is not permitted. Incoming-inspection results should remain with the product records.

Identifying UE24/1-2 for ordering

Use UE24/1-2 for the execution supplied without fittings. Verify the complete suffix, 27 V circuit, connector and installed brake-system diagram; UE24/1-1 is supplied with fittings. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
