Directional Spool Valve 4WEH16HD7X/6EG24ETS2K4/B10 - Bosch Rexroth R901188626

On the 4WEH16HD7X/6EG24ETS2K4/B10 pilot pressure comes from the main circuit and the return runs internally as well. Switching time therefore depends directly on the operating pressure of the plant. Spool symbol D works in two switching positions across four ports, flow is 300 l/min at 280 bar maximum operating pressure and the weight is 10.26 kg.

Benefits

• Pilot pressure taken from the main circuit, no separate control oil source needed
• Spool symbol D, 2 switching positions, 4 ports
• 300 l/min flow at 280 bar maximum operating pressure
• Size 16, weight 10.26 kg
• Subplate mounting to ISO 4401-07-07-0-05
• 24 VDC solenoid actuation, 3-pole connector (2 + PE), NBR seals

Application

As operating pressure rises the main spool reverses faster, which can produce pressure peaks when masses are in motion. In such cases switching time is limited through a pilot restrictor. Permitted figures are listed in the manufacturer data sheet.
