Proportional Directional Valve 4WRKE27E1-500L-3X/6EG24K31/F1D3V - Bosch Rexroth R901548085

Metering large oil volumes cleanly works only with a curve free of steps. The 4WRKE27E1-500L-3X/6EG24K31/F1D3V is linear for that reason, carries 500 l/min nominal flow at operating pressures up to 270 bar and accepts its command as 4...20 mA.

Benefits

• A linear characteristic curve across the whole stroke gives even acceleration up to 500 l/min.
• Spool symbol E1 with a fine control range and 3 switching positions in size 27.
• Internal spool position feedback holds flow at the command value up to 270 bar.
• External pilot oil supply and external return stay independent of working pressure.
• A 4...20 mA command, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804, FKM seals, 19.2 kg.

Applications

The valve controls main cylinders on large presses, die cushions and hoists where motion has to start without jolts. Range maximum flow reaches 1000 l/min, so 500 l/min leaves reserve. FKM seals tolerate higher oil temperatures than NBR.
