Plates cannot be shared with both 2-way and 3-way valves.■KD-2C■KD-2S/2C solenoid valve mounting faceModelHydraulic symbol nameKD-2SNormally openKD-2CNormally closedKD-3SNormally openKD-3CNormally closed■Hydraulic symbol (KD-2S)■Pressure loss characteristics ■KD-2S/2C plate mounting face Operating Maximum operating pressurepressure condition P ≥ TP ≥ A ≥ T■Hydraulic symbol (KD-2C)■KD-2S(C)/3S(C)■KD-3S/3C solenoid valve mounting faceMaximum flow rateMPaL/min70■Hydraulic symbol (KD-3S)Model code structureKD seriesOperating voltageOptionValve type■KD-3S/3C plate mounting face Operating voltageApprox. weight100 VAC200 VAC24 VDC1.3■Hydraulic symbol (KD-3C)DC24:24 VDC2S:2-way valve, normally open 2C:2-way valve, normally closed 3S:3-way valve, normally open 3C:3-way valve, normally closed 1:100 V2:200 VBlank:NoneC:with KCH5:with KT57:with KT79:with KT9AccessorykgMounting bolts:EBH-20 (4 pcs)O-rings:P6 (1 pc) (A)P7 (2 pcs) (P,T)Esperblock (KD Series)KD Series (Poppet Type 2-Way and 3-Way Valves) ● The screw-in lengths for the valve retaining bolts (M6) and the　plate retaining bolts (M8) must be 8 mm and 12 to 15 mm,　respectively. If the screw-in length is insufficient, the valve may　come off, causing injury. ● The tightening torques of the valve retaining bolts (M6) and the　plate retaining bolts (M8) must be 12 to 13 N·m and 20 to 25 N·m,　respectively. Improper tightening of bolts may cause oil leakage　or damage the bolts, by which the KD valve may be detached　resulting in injury.● Since the KD valve has a balance mechanism, observe the pressure balance of each port as follows. Otherwise, the equipment may be　damaged resulting in poor performance. If air remains, pressure may fluctuate or not be raised.　　KD-2S/KD-2C: P ≥ T KD-3S/KD-3C: P ≥ A ≥ T● Do not allow the switching frequency to exceed 20 cycles/min. Otherwise, the equipment may be damaged resulting in poor performance.122KD-2S-1-*
