KE52-2

Operating principle of KE52-2

The electrical input actuates the pilot element and changes pressure acting on the hydraulic distributor. The main element then connects or isolates the required ports in one of two operating positions. 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 hydraulic control systems. Aviation repair and manufacturing catalogues identify KE52-2 as a two-position electrohydraulic valve; exact aircraft and circuit require the parts catalogue. 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 KE52-2 for ordering

Use Latin KE52-2 on the English page and Cyrillic КЭ52-2 on the Russian page. Verify ports, connector, voltage and normal position; KE53, KE54 and KE55 are separate valves. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
