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.

Technical data

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.
