Analysis of surface roughness and profile parameters of graphite packing deposition on valve stems and how this influences frictional performance
Specific stem surface finishes that optimise friction and fugitive emission performance of graphite based control valve packing have been identified and reported; however the reasons behind this varied performance, specifically friction, and the effect of the resultant graphite boundary layer deposit remains unclear.
The James Walker Group is committed to ensuring there is transparency in our own business and in our approach to tackling modern slavery throughout our supply chains, consistent with our disclosure obligations under the Modern Slavery Act 2015.

Compatibility testing of elastomeric materials for rotary sealing use with Environmentally Acceptable Lubricants (EALs) in marine propulsion applications
At James Walker we have been carrying out static immersion testing on EALs for many years, and continue to do so; although during this time it has become apparent elastomeric compatibility can vary between static and dynamic applications.
