800600-1

Operating function of 800600-1

The service fitting is connected during charging and the internal valve isolates the pressurized cavity after the charging device is removed. This compact unit is a charging interface rather than a continuous-flow regulator. Reliable operation depends on clean working media, serviceable seals, correctly connected lines and a calibrated configuration that matches the technical documentation.

Role in the aircraft system

Verified catalogue data gives a working pressure of 22 MPa and a permissible short-duration pressure of 66 MPa. The working medium is air or nitrogen; traces of AMG-10 hydraulic oil are permitted in the documented application. The charging connection corresponds to normal 4316A. Connected units form one operating circuit, but each performs a separate task and must not be presented as interchangeable merely because it is installed in the same system.

Installation and maintenance checks

The valve is used in aircraft pneumatic and accumulator servicing circuits. Its exact installation position and aircraft type depend on the charging line, accumulator or landing-gear chamber identified in the applicable maintenance documentation. Maintenance checks normally cover connection tightness, body condition, contamination and compliance with the specified test limits. Any calibration or adjustment must follow the product passport or approved repair documentation.

Identifying 800600-1 for ordering

Confirm the complete 800600-1 marking, 20 mm connection geometry, specified pressure class and passport before installation. Other 800600-family suffixes may have different media, set pressures or interfaces and are not automatically interchangeable. Other related items are listed in the valves category. An enquiry should identify the required execution, condition, delivery set and supporting documentation.
