The HPK06SE series hydraulically operated directional control valve from Hydac is quite possibly the world’s smallest 5-port pilot-operated spool valve. The screw-in cartridge design is a 3-way, 2-position, flow control valve rated to 5,000 psi and 3.5 gpm. The pilot operated spool valve uses the HYDAC FC06-5 cavity. It features three work ports, separate pilot […]
Learn the latest in mobile hydraulic technologies at FPTC 2019
It’s no secret that mobile machinery is possibly the biggest user of hydraulic technologies. Hydraulic components are ideal because they offer the power density required to move heavy loads used in construction, the precision required in agriculture and the safety of mining. As a result, many of the sessions at this year’s Fluid Power Technology […]
Metal-bellows accumulator handles the extremes
Edge-welded metal bellows accumulators are at the cutting edge of hydro-pneumatic accumulator technology, according to Peter Kloft and Daniel Rau, research and development engineers with HYDAC Technology in Sulzbach/Saar, Germany. Compared with other designs such as diaphragm, bladder and piston accumulators, the gas chamber in metal-bellows units is usually hermetically sealed and the metallic barrier […]
HYDAC’s accumulator facility earns Pressure Equipment Directive certification
Since May 2002, pressure vessels that are manufactured for sale into the European Union are required to conform to the rules established by the Pressure Equipment Directive (PED), also known as “CE.” The PED sets out the standards for the design and fabrication of pressure equipment and other components and assemblies subject to pressure loading. HYDAC’s Accumulator manufacturing facility […]
HYDAC raises the bar in portable hydraulic measurement
Mobile hydraulic measuring equipment requirements correlate with ongoing improvements in machine technology (providing for example, a greater number of functions, shorter production cycles, and higher process precision) and with higher expectations with regards to inspection, testing, fault finding and documentation (such as documentation for final machine acceptance). Furthermore, measurements now need to include events and […]
Sensor readings for fluid conditions
Hy-Trax- Manually Controlled Fluid Sampling System Features and Benefits • Provides Local Visibility to the Fluid Condition of Critical Systems. • Integrated micro VSD, (Variable Speed Drive), pump/motor provides optimal flow for accurate sensor readings in variable conditions. • The HY-TRAX Manually Controlled Fluid Sampling System allows a user to retrieve ISO cleanliness levels from […]
What do you know about hydraulic filter media?
If you’re not familiar with the basics of hydraulic filtration, just wait a week. A week is all it takes to be bombarded by blogs, articles and advertising on the importance of hydraulic filtration—and rightfully so, as it’s the most critical consideration you can make if you’re serious about reliability. I’m guilty of lecturing readers […]
