    Cr vs. CrAg plating

    We have the same part offered by two difference vendors. On one vendors part the plated area is plated with 100% Cr per SEM analysis. The SEM on the other parts show the plating to be 95% Cr and 5% Ag. My question is (with little knowledge of chrome plating) what is the purpose of the...

    Adjustable damping effect

    One reason could be wear. As other parts in the system (or even the damper itself) wear, friction can increase or decrease and the system may need more or less damping force to account for the change. Or in the case of a hydraulic system it may require different damping as the oil heats up...

    pressure relieving proportional valve oscillating

    We are trying to replace a manually controlled pressure reliving valve in a very simple hydraulic system with a Parker AP04G2YP21CN valve. hydraulic circuit However every time we start to energize the valve (increase pressure to the application) the valve oscillates uncontrollably. As we try...

    shuttle valve piston Gtol

    Any suggestions on how best to control the six ground diameters of a shuttle valve piston. The perfect part would have: 1) all the diameters exactly the same 2) all the diameters concentric with each other Thoughts: 1) let one end be datum A, the other datum B and a callout for total runout of...

    Gauge change with altitude?

    yes, altitude compensators, usually located near the widgets... All joking aside as others have said there are many things involved 1) was the oil temperature the same (different temps = different viscosities) 2) assuming you are driving "sportingly" your oil is likely substantially hotter when...

    Tapped M3 Hole

    ScotttyUK, great idea. Yes instead of punching a hole (removing a small diameter of material) for your threads, use that material to give yourself more surface for threads. Just pierce the material and push it through to form in effect a thicker sheet thickness in the area of the hardware.

    Tapped M3 Hole

    You will only get about 1.8 threads so yes you can but it will not take much load, and will likely strip out the threads in short order.
