Valves

Aircraft valves in this catalogue are arranged by exact Part Number, working medium and documented operating function. The selection includes shut-off, check, drain, safety, switching, electromagnetic and electropneumatic devices used in different aircraft systems. Similar housings or a common valve type do not establish the same flow rating, actuation or installation.

Shut-off, switching and pressure-control positions

Examples include the 219K pneumatic shut-off device, 5653T-01 check valve, 5657T air safety valve and 630600 fuel shut-off valve. The 2259T and 610200A are recorded as electrically operated units, while 629600VT is identified as a three-way valve. The complete suffix is retained because it can distinguish the required execution.

Working medium and actuation must correspond

Selection may depend on the fuel, oil, hydraulic or pneumatic circuit, allowable pressure, flow direction, port layout, mounting, actuator and electrical connector. Use values from the exact product documentation rather than general category wording. A valve with the same nominal purpose should not be proposed as an alternative without a documented cross-reference.

• record the full valve designation;
• identify the working medium and circuit;
• state known pressure and flow requirements;
• provide port, actuator and label photographs;
• add quantity and documentation needs.

Request the exact flow-control component

Select the matching listing to ask for confirmation of identity, condition, completeness, records, price and lead time. Pumps and pressure-regulating assemblies are indexed under Aircraft Pumps and Regulators. Components used to clean working fluids appear in Aircraft Filters.
