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.
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).
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 worlds.
The maximum recommended load holding pressure for the H range is 3075 psi (212 bar). The highest cracking pressure for the H range will be 3850-4250 psi (265-
293 bar).
The maximum recommended load holding pressure for the J range is 3850 psi (265 bar). The highest cracking pressure for the J range will be 4800-5300 psi (331-
365 bar).
The percentage difference between the cracking and the reseat values for the LoadMatch™ versions are identical. The setting tolerance is as noted.
Sun load control and counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in
the circuit.
This valve has positive seals between all ports.
This valve has full relief capacity.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
