Directional Spool Valve 4WEH16R7X/6EG24N9ES2K4/B10 - Bosch Rexroth R901293863

Where several actuators work into one return line, back pressure builds up there. Pilot-operated directional spool valve 4WEH16R7X/6EG24N9ES2K4/B10 therefore drains its pilot oil externally, takes pilot supply internally from the main circuit and switches up to 300 l/min.

Benefits

• Internal pilot oil supply, external pilot oil return, pilot drain stays clear of the main return.
• Spool symbol R, three switching positions in size 16.
• 300 l/min at a maximum of 280 bar operating pressure.
• 11 kg valve weight, NBR seals, HL hydraulic fluid.
• Subplate mounting ISO 4401-07-07-0-05, connector 3-pole (2 + PE), 24 V DC.

Application

Its place is the control block of an injection moulding machine or a press line with a shared tank gallery. The external pilot drain keeps switching times steady even while parallel actuators fill the return. Internal supply saves the separate pilot pressure line.
