Directional Spool Valve 4WE6H73-6X/EG220N9K4/A12V - Bosch Rexroth R901371099

The 4WE6H73-6X/EG220N9K4/A12V switches consumer lines in systems with a 220 VDC control voltage. As a direct operated size 6 spool valve with spool symbol H73 it works up to a maximum operating pressure of 350 bar.

Benefits

• Solenoid rated for 220 VDC, so it runs off an existing DC supply without an intermediate converter.
• Spool symbol H73 with 3 switching positions and 4 ports for circuits that need a defined tank connection in mid position.
• Direct actuation without a pilot stage at a weight of 1.8 kg in size 6.
• Maximum operating pressure of 350 bar with FKM seals for hydraulic fluid HL.
• Connector, 3-pole (2 + PE) to EN 175301-803, a widely stocked interface for field coil replacement.
• Subplate mounting to ISO 4401-03-02-0-05 for interchange with any standard size 6 valve.

Application

The valve suits existing plant and special purpose machines where a 220 VDC supply is already run. Symbol H73 holds the consumer in a defined position in mid position while relieving the pump at the same time. The 3-pole connector to EN 175301-803 comes off without special tools during service.
