Pneumatic or hydraulic? It is one of the first questions in any fluid power design, and the answer usually comes down to three main things.

Force. Hydraulic systems pressurize a liquid, which does not compress much at all, so they can hold very high pressures and move very heavy loads in a small package. Pneumatic systems run on compressed air, and air does compress, which caps how much force you can practically get. If the load is heavy, hydraulics usually win.

Speed. Air moves fast and it is forgiving. Pneumatic actuators cycle quickly and can run at high rates all day, which is why they show up in packaging, assembly, and anything with a lot of repetitive motion. Hydraulic systems tend to move with more power but less speed.

Cleanliness. This is the one people underestimate. A pneumatic leak vents air. A hydraulic leak puts fluid on the floor, on the product, or into the process. In food, pharmaceutical, cleanroom, and a lot of packaging environments, cleanliness isn’t an option, it's the standard, so choosing the right design is critical.

There is no universally better option. There is only the one that fits the load, the cycle rate, the environment, and the budget you are actually working with.

If you are somewhere in the middle and not sure which way to go, that is a conversation worth having before the design is locked in. Contact us for more information.

Ever wonder what is actually happening inside a valve? Most of them come down to three parts. There is the body, the internal control element, and the actuator.

Fluid power systems fail for a lot of reasons, but most of them fall into a few familiar categories. Here is what tends to be behind it.

Contamination is a big one. In hydraulic systems, that means contaminated fluid. In pneumatic systems, it is contamination plus moisture or water, and sometimes a lack of proper lubrication if the components require it. Either way, it leads to component failure over time, and improper or skipped preventive maintenance makes it worse.

Sizing matters more than people expect. An actuator that is undersized for its load takes on stress it was never meant to carry. A valve that cannot handle the required flow will always lag behind the speed the system needs. Getting flow and force requirements right up front prevents a lot of headaches later.

Leakage can start at day one. In a pneumatic system especially, it is costly, because compressed air is expensive to produce and any of it escaping into the atmosphere is doing nothing for your process. Sometimes it is as simple as a fitting that was never sealed or tightened correctly, which is why it helps to inspect connections before startup.

And then there are seals. Elastomeric seals degrade with wear, whether from time in service, cycle count, or contamination. Dynamic seals in actuators and valves usually go first. If incompatible oils or chemicals get introduced into the system, that wear speeds up considerably.

If something is not performing the way it should, these are usually worth ruling out first.
