Description
761100-2M Electrically actuated fuel shut-off valve
761100-2M is a electrically actuated fuel shut-off valve that opens or closes a high-flow aircraft fuel line in fire shut-off or crossfeed service. 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 761100-2M
The electric mechanism drives the shut-off member between open and closed end positions. Limit-switch circuits stop the actuator and report valve position; the valve body provides a 70 mm nominal flow passage. 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 as a fire shut-off or crossfeed valve. Public listings associate the 761100-2M execution with an MPK-13A5 electric mechanism. 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 761100-2M for ordering
Retain the final M in 761100-2M and verify the actuator, 70 mm passage, connector and mounting dimensions. It is related to, but not automatically interchangeable with, 761100-2. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
