Directional Spool Valve 4WEH16E7X/6EG24N9K4/B08 - Bosch Rexroth R900952103

Where working pressure swings widely during the cycle, the pilot stage should stay unaffected. The 4WEH16E7X/6EG24N9K4/B08 draws pilot oil from an external source and drains it externally, at a throughput of up to 300 l/min.

Benefits

• External pilot oil supply and external pilot oil return, pilot pressure decoupled from working pressure.
• Spool symbol E in three switching positions across four ports.
• 300 l/min at a maximum of 280 bar in size 16.
• 9,87 kg, interface ISO 4401-07-07-0-05.
• 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803, NBR seals for HL hydraulic fluid.

Application

The version pays off on machines covering a wide pressure range, such as test rigs running from a few bar up towards the ceiling value. An independent pilot circuit keeps shifting times comparable across that range. Four ports and three positions serve one double-acting cylinder.
