Directional Spool Valve 4WEH 16 R7X/6EG24N9S2K4/B10 - Bosch Rexroth R978010982

When a valve is replaced, the pilot oil routing of the old block has to be preserved, otherwise the circuit stops switching. Pilot-operated directional spool valve 4WEH 16 R7X/6EG24N9S2K4/B10 uses external pilot oil supply and external pilot oil return and carries 300 l/min at up to 280 bar.

Benefits

• External pilot oil supply, external pilot oil return, suited to blocks with their own pilot source.
• Spool symbol R, three switching positions on interface ISO 4401-07-07-0-05.
• 300 l/min at a maximum of 280 bar in size 16.
• 9.7 kg valve weight, NBR seals for HL hydraulic fluid.
• Solenoid actuation on 24 V DC, connector 3-pole (2 + PE) according to EN 175301-803.

Technical data

Application

It replaces identically built directional valves in control blocks of presses, hoists and power units that run a separate pilot supply. Since the pilot circuit does not depend on the main circuit, switching still works at low system pressure. All four ports sit on the standard pattern, so the subplate stays as it is.

Manufacturer
