Proportional Directional Valve 4WRLE16E250LJ-4X/VXY/24A1 - Bosch Rexroth R901542669

Large axes with high throughput have to meter finely yet still reverse quickly. This size 16 model of the 4WRLE range answers that with 250 l/min nominal flow, operating pressure up to 350 bar, spool symbol E and a pilot circuit supplied externally as well as relieved externally.

Benefits

• 250 l/min nominal flow against a range maximum flow of 800 l/min, so reserve remains for rapid traverse phases.
• On-board electronics process the ±10 V command value at the valve, an extra amplifier card in the cabinet becomes unnecessary.
• External pilot oil supply plus external return suit power units that carry their own pilot pump.
• FKM seals tolerate higher oil temperatures, the released hydraulic fluid is class HL.
• Mounting pattern ISO 4401-07-07-0-05, mass 12.36 kg, 24 VDC power at a 7-pole connector (6 + PE) to EN 175201-804.

Applications

Typical mounting places are press drives, test rigs for large cylinders and roll adjustment systems. The 3 switching positions with spool symbol E keep the mid position of an existing schematic. With maximum flow at 800 l/min the valve stays inside its control range even during short peaks.
