The 4WRTE32W6-600L-4X/6EG24K31/A1M valve belongs to the 4WRTE Directional Control Valves series from Bosch Rexroth and is used to regulate flow direction and volume in hydraulic automation circuits. Its nominal size of 32 provides large internal passages suited for high-volume lines, while a rated flow of 600 l/min at 5 bar per metering edge supports responsive actuator movement. The recommended maximum flow of 1600 l/min indicates the highest throughput that still limits pressure loss across the body. A pilot-oil demand of 27 l/min drives the spool without overloading the pilot supply. Ports p, a, and b tolerate operating pressures up to 350 bar, and the return line t can withstand 250 bar, matching modern high-pressure systems. Integrated electronics run on a nominal 24 V DC supply, and a peak power draw of 72 VA helps designers size transformers and protection devices correctly.
A command window of ±10 V accepts standard analog signals from motion controllers and feeds a 100 kΩ input stage that minimizes load on the control card. The electronics allow a residual ripple of up to 2.5 Vpp, ensuring stable behavior even with moderate supply noise, and they draw no more than 1.6 A so that fuse ratings remain moderate. Connection is made through a DIN EN 175201-804 (K31) plug, and two PNP position-switch outputs relay spool position to safety or monitoring circuits. The housing meets IP65, protecting internal components against dust and low-pressure water jets for reliable field installation. At 31.5 kg the unit requires rigid mounting brackets but remains manageable for a single technician with lifting aids.
