DAIKIN - Proportional Valves / Servo Valves

Solenoid operated proportional directional control valve (with pressure compensation, multiple valve series)

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.

Open loop control driver (for AC power supply)

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.

Open loop control driver (for DC power supply)

Minor loop control driver (for AC power supply)

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.

DIN terminal type driver for KSP-G02

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.

Open loop control Euro・card type driver

Achieves optimum control of open loop control type KSP 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.
