610200A

610200A electromagnetic fuel valve in aircraft systems

The 610200A is an aircraft electromagnetic fuel valve used for automatic control and shut-off of fuel flow in onboard fuel supply and heating systems. The unit is installed in fuel lines where the system must open or close the fuel path by an electrical command from aircraft control circuits. In operation, the valve works as an executive element: it does not generate the control command itself, but receives it from the relevant onboard automation system and changes the fuel line condition accordingly.

Fuel shut-off function of the 610200A valve

The main function of the 610200A is controlled opening and closing of the fuel line. When the system sends an opening command, the electromagnetic mechanism actuates the valve and allows fuel flow to the connected consumer. When the command is removed or a shutdown condition is reached, the valve closes and stops the fuel supply. This function is used in aircraft systems where automatic fuel control is required during start-up, normal operation, shutdown, or emergency interruption of fuel delivery.

610200A in aircraft heater and auxiliary systems

The 610200A valve can be used in fuel supply circuits for aircraft heaters and auxiliary equipment, including systems associated with KO-50 kerosene-fired heaters and AI-9V auxiliary power unit installations, depending on aircraft configuration. In heater applications, the valve may operate together with temperature switches and control relays that manage the start, combustion, and shutdown sequence. In auxiliary systems, it is used where fuel must be supplied only under controlled operating conditions and reliably shut off when the system is stopped.

System integration of the 610200A with automation circuits

The 610200A is controlled by the aircraft DC electrical system and operates as part of an automated fuel control circuit. It may be connected with switches, relays, temperature protection elements, start logic, and shutdown circuits depending on the installed system. For example, in heater-related applications, fuel shut-off may be controlled by thermal protection devices that interrupt the circuit when unsafe temperature conditions occur. Correct wiring and control logic must always be checked against the aircraft wiring diagram and the technical documentation for the specific installation.

Working media and operating conditions for 610200A

The valve is designed for aviation fuel media and is specified for several aircraft fuel grades. According to the passport data, the 610200A works with aviation fuels used in onboard systems and is intended for operation across a wide temperature range. The body, sealing surfaces, and electromagnetic actuation system must maintain reliable operation under vibration, fuel pressure, temperature variation, and aircraft service conditions. For this reason, the valve should be inspected not only for electrical continuity, but also for mechanical condition, sealing quality, and freedom of movement.

Identification and supply of the 610200A fuel valve

For procurement, repair, or replacement, the valve should be identified by the full designation 610200A and matched with the aircraft parts catalog, fuel system documentation, and applicable heater or auxiliary unit manual. The unit may be supplied as an aircraft technical item with passport or operational documentation. Completeness must be confirmed separately, because the valve may be supplied as a standalone unit without additional fittings, adapters, or installation hardware. Before installation, the technical condition, storage status, documentation, and compatibility with the target system should be verified.
