Description
GA-186M/3 Hydraulic safety relief valve
GA-186M/3 is a hydraulic safety relief valve that protects the hydraulic circuit by opening a relief path when pressure exceeds the calibrated limit of the /3 execution. 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 GA-186M/3
Pressure acts on the pilot and main valve elements. When the calibrated threshold is exceeded, the pilot changes the pressure balance, the main member opens the path to return and limits further pressure rise. 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-system pressure-protection circuit. Public catalogues identify GA-186M suffix variants as safety valves, while the exact aircraft and setting for GA-186M/3 require its passport. 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 GA-186M/3 for ordering
Keep the slash and final 3 in GA-186M/3. Verify the calibrated opening pressure and do not substitute GA-186M, GA-186/3 or another suffix by appearance. Other related products are listed in the valves category. An enquiry should state the complete designation, execution, condition, delivery set and required supporting documents.
