From initial engineering and design to manufacturing, assembly and test...

PneuDraulics' employees are focused on providing the highest quality hydraulic valves, components and assemblies available to the aerospace industry.

For over 50 years our commitment to quality has been uncompromised.

All phases of PneuDraulics' operations are performed in accordance with ISO 9001:2015 and AS9100:2016 standards.


The Pneudraulics Engineering Department utilizes the latest computer aided design and analysis software available for our product complexity. Simple 2-D design is accomplished on Auto Cad 2000 and archiving is done on Auto Cad. Solid models utilize SolidWorks software, which will also produce Auto Cad compatible detail drawings. Finite element analysis (FEA) for 2-D work is accomplished using Algor software with the Auto Cad drawings.


3-D FEA is performed on the CosmosWorks software program and works in conjunction with SolidWorks. Pneudraulics has a library of hydraulic component designs that have been created over the last 50 years for virtually every major aircraft program.

The engineering laboratory is fully equipped for virtually all developmental and qualification testing. Three environmental chambers capable of -80° fahrenheit to +300° fahrenheit are used for both fluid and ambient temperature testing. Test fluids are Skydrol, MIL-PRF-5606 and Stoddard solvent.
