Directional Spool Valve 4WEH16J7X/6EG24N9EK4/B10 - Bosch Rexroth R901012578

Where a return filter or return cooler keeps the tank line under load, an internally drained pilot stage loses switching margin. The 4WEH16J7X/6EG24N9EK4/B10 combines internal pilot oil supply with external pilot oil return and passes up to 300 l/min at 280 bar.

Benefits

• Internal pilot oil supply, external pilot oil return, keeping the pilot drain clear of the main return line.
• Spool symbol J in three switching positions across four ports.
• Up to 300 l/min at a maximum of 280 bar in size 16.
• 24 VDC supply voltage through a connector, 3-pole (2 + PE) according to EN 175301-803.
• 9,9 kg on subplate mounting to ISO 4401-07-07-0-05 with NBR seals.

Technical data

Application

The valve suits machines whose return line carries a filter or a cooler and is therefore never fully unloaded. A separately routed pilot drain keeps switching times repeatable. HL hydraulic fluid and NBR seals cover ordinary machine tool duty.
