Directional Spool Valve 4WEH32Y6X/6EG24N9K4 - Bosch Rexroth R901370973

From about size 25 upwards, solenoid force is no longer enough to move a main spool directly. This valve solves that with a pilot stage and switches up to 1100 l/min in size 32. The main spool follows symbol Y in 2 switching positions, operating pressure reaches 280 bar.

Benefits

• Flow up to 1100 l/min in size 32 at an operating pressure of up to 280 bar
• Symbol Y with 4 ports in 2 switching positions
• External pilot oil supply with external pilot oil return, keeping pilot and return pressure separate from the main circuit
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803
• Subplate mounting to ISO 4401-10-09-0-05 with NBR seals for HL fluid
• Mass 35.42 kg

Applications

The valve controls large cylinders in presses, forging plants and plastics machinery. Separate pilot oil routing suits systems with back pressure in the return line or a pilot circuit that is protected on its own.
