By Ron Marshall Jeff had been a maintenance technician long enough to know that low-pressure complaints rarely arrived alone. When one operator reported sluggish pneumatic cylinders, others usually followed with complaints about weak air tools, slow actuators, and inconsistent machine performance. That was exactly what happened one Monday morning in the assembly area, where production […]
Type 625 volume booster provides faster response and stable valve control
ControlAir LLC has released its type 625 volume booster, a compact pneumatic relay designed to improve the speed and performance of pneumatic control valve actuators. These pressure regulation devices use pilot pressure rather than a spring or adjustment thread to provide force balance when opening the supply valve. Installed between a valve positioner and pneumatic […]
Putting the people first in fluid power
I’ve just returned from two intensive days at the Danfoss Distributor Meeting, where I had the opportunity to learn what Danfoss Power Solutions is homing in on with its distribution customer base. And while it was interesting and informative to learn about its updates to its industrial lines or electrification solutions, I was hit with…
Yet another reason hydraulics is superior
If you’re tired of my missives about cars, this is your chance to click away. Conversely, if you enjoyed my article on enshittification (see our October issue and live link here), this example will make you pine for the good old days of automotive technology. “But Josh, what does hydraulics have to do with cars?…

IoT-ready sensor fundamentals
Sensors are not as talked about as some other Internet of Things technologies, despite their critical role within the Industry 4.0 community at large. Sensors are technologies in fluid power that read, interpret, and transmit data based on one or more criteria important to observe: pressure, temperature, flow, contamination, water saturation, and vibration, to name…
Hydraulic and pneumatic manufacturers advance through connectivity
As many know, there are few ways to improve upon pneumatic and hydraulic technologies. They already offer high pressures that are unmatched by competitive technologies, reliability, precision and much more. While efficiency gains are always needed, an area where the industry is seeing improvements is with connectivity. On both the mobile and industrial side, connected…
The robots aren’t ready to take over yet
At the NFPA’s IEOC back in August, the association brought together leaders from OEMs and market intelligence for a panel discussion on what the future holds for mobile machinery and the part hydraulics will play. Integrated systems were a huge part of the discussion, but where this discussion led revealed that OEMs are not really…
Energy Efficiency in Hydraulics: Challenges and Solutions
Hydraulic systems are a fundamental technology in manufacturing and industrial operations. Widely used in applications such as metal forming, plastics processing, heavy equipment, and automated production lines, hydraulics are valued for their high-power density, robustness, and reliability. As energy efficiency becomes an increasingly important consideration across industries, attention is turning toward how hydraulic systems can…
Actuator fundamentals: from ballscrews to cylinders
An actuator is any device that converts one form of energy into physical, linear force. From a fundamental definition of the word, one could assert that motors are also actuators, but from a practical perspective, the machine world agrees on the linear definition. The primary source of energy can be pressurized air or liquid, electricity,…
Donaldson reservoir headspace dryer controls moisure, extends fluid life
Donaldson Company Inc. has introduced the Donaldson Hy-Pro Reservoir Headspace Dryer. The Reservoir Headspace Dryer (RHD) removes free, emulsified, and dissolved water from hydraulic and lubrication fluids in their reservoirs by generating dry air and circulating it through the headspace. The process enables moisture to transfer from the oil to the dry air stream. The […]
O-ring failure modes in hydraulic systems: identification, root causes and prevention
Contributed by Xing Hong, Founder, WRKR Seal Hydraulic systems depend on reliable sealing at every connection point. When an O-ring fails in a hydraulic circuit, the consequences range from minor fluid weeping to catastrophic pressure loss, environmental contamination, and unplanned downtime that costs thousands of dollars per hour in heavy industry. Yet a significant share […]
Bladder accumulator fundamentals
Bladder accumulators are an industry-standard choice, as commonly available as D03 valves or NFPA-style hydraulic cylinders. Your outside sales team is always happy to see them in a factory, because everyone offers an option to either repair or replace them.
