The new DRV screw-in, poppet type, direct-acting cartridge-style hydraulic relief valve from Doering is designed for use as a pressure limiting device for common hydraulic circuit protection. The DRV blocks flow from port 1 to port 2 until sufficient pressure is available at port 1 to force the poppet from its seat. The cartridge offers…

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 […]

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…

With the support of experts from the ATEX world, ATAM has self-certified…

Lumber processing technology has come a long way and requires attention to achieve precision and speed. To stay competitive as lumber demand increases, industry expert Carl Dyke shares guidance on how to keep sawmill hydraulic systems running optimally. As part of its Timber Products Output (TPO) mill survey, the U.S. Department of Agriculture’s Forest Service…

Emerson recently announced its new Aventics Series 625 Sentronic Proportional Pressure Control Valves. With a control deviation of less than 0.5%, the new valves are designed to deliver highly accurate, electronic proportional pressure control and provide the flexibility needed to support sophisticated pneumatic control engineering applications. Data acquisition software (DaS) software included with Series 625 […]

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…

  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…

DGD Fluid Power announces the release of the newest addition to its Cartridge Flow Transmitter (CFT) product line: the CFT-Max. Designed to meet the increasing demand to monitor hydraulic flows on mobile equipment, the CFT-MAX is J1939 compliant with an IP69 rating. Flows up to 150 gpm and a 6,000 psi pressure rating allow the…

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…

Moog Inc. is proud to announce the launch of two new direct operated valve series: the D93x servo-proportional valve series and the D92x proportional valve series. Each series, with its unique features and capabilities, is designed to boost machine reliability and optimize costs for machine builders. The D93x servo-proportional valve series comprises the D936 (ISO…

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 […]

ATAM has recently completed the replacement of the majority of its overmoulding presses at the Agrate Brianza  plant, adding six new machines, each one with a different tonnage.

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…

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 […]

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…

By Michael Pyper Bucher Hydraulics High hydraulic performance is crucial in mobile machinery. Especially in this era of increasing electrification, hydraulics remains vital. This is particularly true for agricultural and forestry machines where compact installation and weight optimization are essential. Fluid power plays a significant role in energy efficiency and, when intelligently combined, electric and […]
