Load-Sensive Hydraulic Proportional Directional Valves1

Festures:

Proportional valve is a load sensed stackable valve with interchangeable pressure compensation styles.
In the same main section body, inserting different spring and compensator, the valve can be either precompensated
or post compensated. As we know, post compensated valve system has flow sharing capability.
Due to using pressure compensation in each section, system flow is independent with load. All proportional valves
in this series have load-sensing capabilities. We can also choose different cartridges for the main section assembly
to accomplish different functions. This valve series adapted modular design. The system designer can choose different
modules to design different complex systems. Main valve spool is designed to satisfy with the customer’s
requirements, which provides excellent flow characteristics and very low flow force.
