Directional Spool Valve 4WEH16J7X/6EG24N9ETK4/B10P4,5 - Bosch Rexroth R901138846

When a centre position unloads port P, an internally piloted valve loses its oil supply. The 4WEH16J7X/6EG24N9ETK4/B10P4,5 in size 16 holds 4.5 bar at its inlet through a pre-load valve, so it still switches reliably at up to 300 l/min in an unloaded circuit.

Benefits

• 4.5 bar pre-load valve in the inlet secures pilot pressure with an internal pilot supply.
• Internal pilot oil supply and internal pilot oil return, no external pilot lines required.
• Spool symbol J in three switching positions across four ports.
• Up to 300 l/min at a maximum of 280 bar in size 16 to ISO 4401-07-07-0-05.
• 9.86 kg, 24 VDC solenoid actuation with a connector to EN 175301-803.

Application

It pays off in circuits that unload to tank through a centre position, for example presses running an idle loop. A pre-load valve keeps pilot pressure up without any external pilot line being laid.

Manufacturer

Bosch Rexroth lists this pilot-operated directional valve 4WEH16J7X/6EG24N9ETK4/B10P4,5 under material number R901138846. Data sheets RE 24751 and RE 07600-B show characteristic curves, installation dimensions and the connection diagram. Suffix P4,5 in a type code stands for a built-in pre-load valve.
