Proportional Directional Valve 4WRZ10W8-50-7X/6EG24N9K4/D3V - Bosch Rexroth R978911535

External electronics keep the valve itself lean and move the control parameters into the cabinet. The 4WRZ10W8-50-7X/6EG24N9K4/D3V follows that principle and controls 50 l/min nominal flow.

Benefits

• Electrical with external electronics, connected through a connector, 7-pole (6 + PE) according to EN 175201-804.
• 50 l/min nominal flow, up to 170 l/min in size 10.
• Spool symbol W8 in three switching positions with four ports.
• External pilot oil supply and external pilot oil return through X and Y.
• 315 bar maximum operating pressure, FKM seals, mass 8.24 kg.

Applications

It is used on axes with controlled speed, for example on test rigs, presses and machine tools. Because the amplifier sits in the cabinet, it stays away from the heat and vibration at the manifold. The released hydraulic fluid is HL.
