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 […]

New open-center directional valve group for mobile machinery
Danfoss Power Solutions today announced the launch of its DVG family of hydraulic valves, a new line of open-center directional control valves for mobile machinery. Currently available in North, Central, and South America, the valve group brings a new level of quality and performance as well as rapid and reliable delivery to a competitive market. […]
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 […]
Differential lock valves improve fuel efficiency and control
For decades, spool-type flow dividers have proven themselves well in the differential locks of hydraulic traction drives. In recent years, however, the demands of mobile machine operators have risen to a new level. For example, market requirements now include: • More intuitive operation. • Better vehicle control, particularly when driving under difficult conditions. • Optimization […]
Smart management, smart control blocks
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 […]
Expanded tractor valve platform enables use on wider range of models
Danfoss Power Solutions has enhanced its tractor valve platform with additional electrohydraulic module sizes as well as new mechanical modules, enabling the valve to be used on a wider range of tractor models. Proven in farm fields for more than 20 years, Danfoss’ tractor valve provides rear implement, front implement, and front loader control. Built […]
Compact check valves fit tight installation spaces
Check valves are proven components that allow media to flow in only one direction and prevent backflow in the opposite direction — similar to diodes in electrical applications. For years, the engineers at Bucher Hydraulics based in Dachau, Germany, have continuously optimized this unobtrusive component, which is often concealed inside hydraulic blocks. For instance, the […]
Pursuing victory in the America’s Cup
The America’s Cup is one of the world’s most prestigious and oldest sailing competitions. It has a long and storied history, dating back to 1851 when the first race was held around the Isle of Wight in the U.K. The yacht “America” won the trophy, which is how the race got its name. Since then, […]
PVG 48 pre-compensated proportional control valve for mobile machinery
Danfoss Power Solutions has extended its PVG valve portfolio with the addition of PVG 48, a pre-compensated proportional control valve for mobile machinery. Designed for applications requiring flow rates of up to 180 liters per minute (47.6 gallons per minute), PVG 48 provides customers with a right-sized option between the existing PVG 32 and PVG […]
Check valves serve critical role in work trucks with aerial work platforms
Even when workers follow job site safety protocols to a T, emergencies can happen. And when working with large, powerful machines in dangerous or challenging environments, things can become catastrophic quickly. However, there is one small but critical machine component that can help minimize equipment damage, limit project downtime and keep workers safe – the […]
