Description
761100-2 Electrically actuated fuel shut-off valve
761100-2 is a electrically actuated fuel shut-off valve that opens or closes an aircraft fuel line when used as a fire shut-off or crossfeed valve. The unit is an independent functional component of the applicable onboard system. Selection should be based on the complete designation, working medium, setting and installation diagram rather than appearance alone.

Operating principle of 761100-2
An MPK-13A5 electric mechanism moves the shut-off element to its commanded end position. The installed wiring and limit-switch circuit provide control and position indication according to the aircraft diagram. 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 fuel-supply system, including fire shut-off and crossfeed positions where the 761100-2 execution is specified. The exact aircraft and line require the illustrated 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 761100-2 for ordering
Confirm whether the required unit is 761100-2 or 761100-2M and whether the MPK-13A5 mechanism is included. The suffix M identifies a separate execution and should not be omitted. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
