Directional Spool Valve 4WEH 16 D7X/6EG96N9ETS2K4/B08 - Bosch Rexroth R978001057

Where an axis is only reversed between two defined positions, a two-position valve is enough and saves the mid-position logic. The pilot-operated directional spool valve 4WEH 16 D7X/6EG96N9ETS2K4/B08 does exactly that in size 16 with spool symbol D, up to 300 l/min flow and 280 bar operating pressure, driven from 96 VDC.

Benefits

• Two switching positions with spool symbol D on four ports.
• Flow up to 300 l/min, operating pressure up to 280 bar, connection diagram ISO 4401-07-07-0-05.
• Supply voltage 96 VDC, connector 3-pole (2 + PE) to EN 175301-803.
• Internal pilot oil supply and internal pilot oil return, no separate pilot lines required.
