Directional Spool Valve 4WEH 16 T7X/6EG24NTK4 - Bosch Rexroth R978915054

How an axis behaves with the solenoid de-energised depends on the spool symbol. The pilot-operated 4WEH 16 T7X/6EG24NTK4 is built to symbol T, offers three switching positions across four ports and carries up to 300 l/min.

Benefits

• Three switching positions to symbol T, four ports on port pattern ISO 4401-07-07-0-05.
• External pilot oil supply, internal pilot oil return, so the pilot oil drains through the manifold tank gallery.
• 300 l/min at a maximum of 280 bar operating pressure in size 16.
• 8.9 kg, light enough to change on the manifold by hand.
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803, NBR seals.

Applications

System builders fix the symbol variants of a series early, because the manifold is machined to suit. Symbol T is among the versions that appear in circuit diagrams for plants with several consumers fed in parallel. Since the mounting dimensions follow ISO 4401-07-07-0-05, the valve can be exchanged in the field for another symbol variant of the same size without touching the manifold.
