Directional Spool Valve 4WEH16E7X/6EG205N9EK4/B10P4,5 - Bosch Rexroth R901523713

Suspended loads and clamping cylinders must not give way at standstill, so the mid position has to be tight. The pilot-operated directional spool valve 4WEH16E7X/6EG205N9EK4/B10P4,5 blocks through spool symbol E and passes up to 300 l/min in size 16 at 280 bar.

Benefits

• Spool symbol E with closed centre, three switching positions on four ports.
• Flow up to 300 l/min at an operating pressure of up to 280 bar.
• Internal pilot oil supply with external pilot oil return.
• Supply voltage 205 VDC, connector 3-pole (2 + PE) to EN 175301-803.
• NBR seals for HL hydraulic fluid, ISO 4401-07-07-0-05, weight 9.75 kg.

Technical data

Application

The valve is used on lifting, clamping and positioning axes that have to stay put between movements. Leak-free holding additionally calls for a seat valve, but the closed spool centre clearly reduces drift. Pilot pressure is taken internally and drained externally.
