Proportional Directional Valve 4WRZ32E520-7X/6EG24K4/D3M - Bosch Rexroth R900716549

Large cylinders in press lines, lifting gear or materials testing machines need plenty of oil and still a fine command. The 4WRZ32E520 delivers 520 l/min nominal flow, copes with up to 1600 l/min maximum flow and works at up to 350 bar operating pressure. Spool symbol E switches across three positions and four ports, while a built-in pressure reducing valve holds the pilot pressure steady.

Benefits

• 520 l/min nominal flow in size 32, maximum flow 1600 l/min
• Operating pressure up to 350 bar, hole pattern ISO 4401-10-09-0-05
• External pilot oil supply and external pilot oil return, so the control circuit can be filtered and protected on its own
• Spool symbol E with three switching positions and four ports
• NBR seals for HL class hydraulic fluid
• 43 kg unit weight, driven by external electronics at 24 VDC

Application

The valve suits plants where one power unit feeds several large consumers, such as press lines, hydraulic test benches and steel processing equipment. External pilot supply allows the control oil to be taken from a separate, finely filtered circuit. A 7-pole connector (6 + PE) to EN 175201-804 is provided for the amplifier electronics.
