When should you use counterbalance valves?
By Josh Cosford, Contributing Editor Counterbalance valves are an ingenious invention used to control runaway loads caused by mass or gravity attempting to push or pull outside of intentional movement. There are many ways to control a load or prevent it from moving, such as flow control valves or pilot-operated check valves. However, a counterbalance […]
Increasing hydraulic efficiency outside of pump selection
By Josh Cosford, Contributing Editor Let’s be clear that pump selection is the quickest way to increase hydraulic system efficiency, as one can easily improve your energy ROI by 15% or more simply by upgrading from a gear to a piston pump, for example. But pumps aren’t the only way to increase your efficiency, thereby…

How do three-way hydraulic valves work?
By Josh Cosford, Contributing Editor Three-way valves, common and versatile tools in fluid power, demonstrate their precision by effectively diverting, selecting, or mixing three flow paths as the circuit requires. These valves, available in lever or solenoid actuation, are widely used for directional control. Their construction style varies, ensuring suitability for diverse applications. The three-way…
Troubleshooting challenge: new valve locks up on rod threading machine
By Robert J. Sheaf, Founder, CFC Industrial A customer of mine has a machine that threads both ends of a straight piece of rod stock which then is fed into a second machine to bend it in a “U” shape. This creates a clamp for various round pipe sizes. They had a problem with…

What’s in the cards for leakage?
Will hydraulics ever get past the leakage issue? I’ve heard people discuss this question countless times over the three decades that I’ve worked in and written about the technology. Time and time again, people bash this useful technology because of perceived problems with leakage. I have encountered this negative talk on factory floors, in educational…

Proportional valves make crane precision possible
Cranes lift heavy loads, and precise control of the lifting process is paramount for safety and efficiency. Proportional valves fine-tune the hydraulic pressure applied to the lifting mechanism so that operators can control speed and force while lifting and lowering. In 2021, Australian crane manufacturer Franna sought to improve the performance of its MAC 25 […]

7 signs your hydraulic valve has failed
By Josh Cosford, Contributing Editor There are very few hydraulic systems operating without directional valves, and aside from modern technologies that can make do with a servo-driven pump and a single actuator, you’ll be hard-pressed to think of a way to control actuators without them. They are responsible for managing the flow and direction of…
Clippard release AIV series air-piloted media isolation valves
Like Clippard’s NIV and PIV lines of isolation valves, the AIV series features Clippard’s unique multi-functional valve stem design for longer life and minimal dead volume. The difference with the AIV series is that is that it also provides the added benefit of air operation, which is — by definition — intrinsically-safe. No solenoid means […]
Is the sequence valve obsolete?
By Josh Cosford, Contributing Editor We don’t hear much anymore regarding sequence valves, and probably for good reason. A sequence valve is like a self-regulating inline relay that opens when work pressure overrides the spring setting. It’s a form of hydraulic automation that provides sequential operation for two or more functions using one fluid supply…
