Directional Spool Valve 4WEH16HD7X/6EG24N9ES2K4/B10 - Bosch Rexroth R900720896

When back pressure stands in the tank line, the pilot stage should not feel it. The 4WEH16HD7X/6EG24N9ES2K4/B10 takes its pilot oil internally from the main channel but drains it externally through its own Y port, switching 300 l/min to symbol D.

Benefits

• External pilot oil drain, the pilot circuit stays independent of return line back pressure.
• 300 l/min rated flow, maximum operating pressure 280 bar.
• Symbol D across four ports in two switching positions.
• 10.32 kg on interface ISO 4401-07-07-0-05.
• 24 VDC solenoid, 3-pole connector (2 + PE), NBR seals for hydraulic fluid HL.

Technical data

Application

Systems with a return filter, a cooler or a long tank line build up a pressure that delays the reset of the pilot stage. The separate Y drain avoids this. At 300 l/min the switching time therefore stays stable even when several consumers discharge into the tank at once.
