Directional Spool Valve 4WEH 16 G7X/6EG24NK4 - Bosch Rexroth R978910380

A size 16 manifold is machined to the standard port pattern ISO 4401-07-07-0-05 and then accepts any valve of that size. The pilot-operated 4WEH 16 G7X/6EG24NK4 occupies such a station and carries up to 300 l/min.

Benefits

• Standard port pattern ISO 4401-07-07-0-05, subplate mounting with no piping of its own.
• Three switching positions to symbol G across four ports.
• 300 l/min rated flow at a maximum operating pressure of 280 bar.
• External pilot oil supply and external pilot oil return, pilot pressure independent of working pressure.
• 8.9 kg, actuation at 24 VDC through a 3-pole connector (2 + PE), NBR seals for HL hydraulic fluid.

Applications

Where a manifold gathers several axes, the standard mounting face saves piping, leak points and assembly time. The external pilot circuit suits machines that already carry a small pilot pump or an accumulator, because pilot pressure is then present even while the working circuit is unloaded. A field change needs four screws undone, and at 8.9 kg the valve is easy to handle.
