Sun Hydraulics Corporation introduces its next-generation cartridge family that offers an average energy savings of 30% over standard counterbalance valves and offers stability across many applications.
These new patent-pending LoadAdaptive counterbalance valves – an evolution of and direct replacement for Sun’s CB series of valves – are multi pilot-ratio valves that provide improved stability and highly efficient operation. By adapting to operating conditions – providing high pilot ratios for efficiency when possible and low pilot ratio and low flow gain for stability when required – this new family offers a solution for many load-holding applications.
Using the three different pilot ratios across the operating range creates the performance you need, delivering the highest possible pilot ratio and flow gain while maintaining stability. The LoadAdaptive counterbalance valve can replace a standard CB series counterbalance valve wherever energy savings are important. What this means is you can improve either efficiency or stability without having to trade one for the other. You can now use a new LoadAdaptive valve in systems with cylinders that require lower pilot-ratio counterbalance valves for stability, effectively reducing cylinder pressure by about 20% before the valve begins to control the cylinder movement. Or you can replace a higher pilot-ratio counterbalance valve with a 3:1 LoadAdaptive valve for more stability and not sacrifice efficiency.
A range of system benefits include:
Run actuators faster under no-load conditions
Increase battery life
Reduce heat generation
smaller prime movers in your system
The following three models are available now:
CECA – a 15-gpm standard-capacity valve with a 3:1 pilot ratio
CEBC – a 10-gpm semi-restrictive valve with a 3:1 pilot ratio
CEBA – a 5-gpm restrictive valve with a 3:1 pilot ratio
A series of 1.5:1 pilot-ratio LoadAdaptive counterbalance valves with be available soon. The LoadAdaptive family continues to expand Sun’s selection of counterbalance valves.
