Proportional Directional Valve 4WRZE25E325-7X/6EG24K31/A1D3V - Bosch Rexroth R901259316

Spool symbol E blocks all four ports in mid position, so a loaded cylinder stays put. In this build the 4WRZE25E325 passes up to 325 l/min of nominal flow and takes its pilot oil from a separate line.

Benefits

• On-board electronics close the position loop themselves, so no separate amplifier is needed in the cabinet
• Command value Analog, command value ±10 V on a 24 VDC supply, Connector, 7-pole (6 + PE)
• FKM seals matched to HL hydraulic fluid
• Subplate mounting to ISO 4401-08-08-0-05, size 25 interface, weight 20.62 kg
• Rated at 325 l/min nominal flow with a flow reserve of 870 l/min

Applications

This version fits everywhere a cylinder must not creep down while at rest, for example on hoists and press tables. External pilot routing lets the pilot stage run on its own filtered circuit. At 20.62 kg this is one of the heavier size 25 builds.
