Directional Spool Valve 4WEH32HD6X/6EG24N9ESK4/10B10 - Bosch Rexroth R901285316

Above roughly 1100 l/min the pressure drop across the directional valve sets the cycle time of the entire axis. The size 32 4WEH32HD6X/6EG24N9ESK4/10B10 carries that flow across four ports and switches it in two positions to symbol D. Pilot oil is taken internally while the pilot return is routed externally.

Benefits

• 1100 l/min flow in size 32, dimensioned for the main axes of large machines
• Two switching positions to symbol D, an unambiguous assignment in the sequence program
• Operating pressure up to 280 bar with NBR seals and HL hydraulic fluid
• Internal pilot supply with external return, so the return can be kept free of back pressure
• Control at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• Mounting pattern ISO 4401-10-09-0-05 at 36.99 kg valve mass

Technical data

Application

The valve sits in manifolds of forging presses, sheet metal lines and hydraulic power units of several hundred kilowatts. An external pilot return is advisable when the tank port of the main stage carries back pressure and the pilot stage should stay separated from it.
