20160076557 | COUNTERBALANCE VALVE WITH DUAL OR TRIPLE PILOT RATIO - Novel Counterbalance valves, more particularly, to counterbalance valves that provide hold, capture, and motion control benefits of prior art CB valves while improving upon one or more performance characteristics of current CB valves are herein disclosed. The novel counterbalance valves are useful, inter alia, for providing good system stability across a range of load pressures and/or reducing power consumption (improving energy efficiencies) as compared with prior art devices. | 03-17-2016 |
20130233409 | DYNAMICALLY ADJUSTING COUNTERBALANCE VALVE - A counterbalance valve is provided with load-sensing, hydro-mechanically setting, features. The counterbalance valve relief setting changes dynamically based on the load pressure at the load port of the counterbalance valve. | 09-12-2013 |
