Product Description

These valves are self-setting counterbalance valves which combine multiple functions in one package; reverse free flow, load, and thermal relief. The check allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting pilot function self adjusts to approximately 1.3 times the load induced pressure up to the thermal relief setting.The LoadMatch™ control allows the setting of the valve to dynamically adjust in response to load pressure, while still providing a fixed thermal relief setting. The control creates a dynamic setting that is lower than the thermal relief setting, but is never more than necessary to provide safe, reliable load control. Also, since the dynamic setting is lower than the thermal relief setting, the pilot pressure required to open the valve is typically lower than other load control valves with similar thermal relief settings.LoadMatch™ control allows for lower pilot pressures under most loading conditions than other counterbalance valves with similar thermal relief settings.Pilot pressures for LoadMatch™ control are nearly identical for any load pressure in the operational range.

The LoadMatch™ control utilizes an integral bypass damper that enables the valve to adjust rapidly to increasing load pressures for safe load control, but slows the reduction of setting for stability.All 3-port counterbalance, load control, and pilot-to-open check cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size). Note: This valve has a larger hex size than what is typical for its cavity and special consideration should be given in existing applications.This valve is functionally a 3-port counterbalance valve. It seats as a poppet valve and modulates as a spool valve, offering the best of both valve types.These valves are capable of modulating over a broader range of flows than the pure poppet designs. The longer stroke allows us to incorporate a uni-directional damping device that smooths the opening and lets the valve close quickly.Backpressure at port 2 adds to the effective relief setting at a ratio of 2 times the backpressure.The maximum recommended load holding pressure for the G range is 4620 psi (319 bar). The cracking pressure for the G range will be 5800-6350 psi (400-438 bar).
