Stacking type multi-control valves that are equipped with the bypass type pressure compensation function and show proportional flow rate characteristics. The pump pressure can be changed according to variation of the load pressure, with the excess flow bypassed to the tank.
Stacking type control valves that show pressure compensated type proportional flow rate characteristics and control the flow rate in proportion to electrical current regardless of the load level. Combining the valve with a variable displacement pump enables construction of a power match circuit that outputs the required pressure/flow rate.
Achieves optimum control of open loop control type solenoid operated proportional control valves. The constant current characteristics suppress the power supply voltage fluctuation, and the output current fluctuation due to temperature rise of the solenoid, to almost zero.
Achieves optimum control of minor feedback control type LEM* valves by detecting the spool position with a differential transformer. The constant current characteristics suppress the power supply voltage fluctuation, and the output current fluctuation due to temperature rise of the solenoid, to almost zero.
Achieves optimum control of KSP-G02. The constant current characteristics suppress the power supply voltage fluctuation, and the output current fluctuation due to temperature rise of the solenoid, to almost zero.
