Directional Spool Valve 4WEH 16 HE7X/6EG48N9ETSDAL/B08 - Bosch Rexroth R978905589

Large flows can no longer be redirected by a solenoid alone. The pilot-operated directional spool valve 4WEH 16 HE7X/6EG48N9ETSDAL/B08 uses internal pilot oil for that, switches symbol E in three positions and handles up to 300 l/min.

Benefits

• Up to 300 l/min in size 16 at a maximum operating pressure of 280 bar.
• Internal pilot oil supply and internal pilot oil return, no external pilot line is needed.
• Symbol E in three switching positions with four ports to connection diagram ISO 4401-07-07-0-05.
• 48 VDC solenoid actuation with cable gland and a 3-pole connector (2 + PE) to EN 175301-803.
• 8.9 kg weight with subplate mounting, NBR seals for HL hydraulic fluid.

Applications

The valve controls main axes on presses, injection moulding machines and large clamping fixtures moving several hundred litres per minute. Symbol E determines the behaviour in mid position. Internal pilot oil routing simplifies the piping, because no separate pilot circuit has to be run.
